Which line running through (3,4) is perpendicular to y = -3x + 4?
y = -3x + 13
y = 3x - 5
Where does cross the y axis?
Which equation runs through points (1, 6) and (-1, 2)?
y = 2x + 4
y = -2x + 8
y = -4x + 10
y = 4x + 2
To compute for m in the problem use and
The straight-line equation in the slope-intercept form applies, that is:
y = mx + b, where m is the slope and b is the value of y when x = 0 (the y-intercept)
Initially, we know that the equation will be something like this:
y = 2x + b
Since there is only one choice that fits this description, save time by choosing that answer.
However, if there were more than one choices that fit the description, or if it isn't a multiple choice problem, continue:
We need to know b, which we compute by plugging in either of the points given:
If we use (x, y)=(-1, 2):
y = 2x + b
2 = 2(-1) + b
Therefore, the correct equation is:
y = 2x + 4
TIP: you can check by using the other given point, (1, 6).
Jim is filling his rectangular pig trough full of slop. The trough is 3 ft wide, 8 ft long, and has a depth of 4 ft. One of the piglets jumps in the trough and the slop rises 2.8 inches.
What is the volume of the trough?
The information about 2.8 inches rise in slop is unnecessary because you are asked to find the volume of the trough, not that of the slop.
Be careful to be aware of, and discard, any irrelevant information given in test questions.
A ladder is leaning against an 18 ft building. The bottom of the ladder is 8.5 ft from the building.
Approximately how tall is the ladder?
TIP: It's easy to arrive at the answer ,
but not as easy looking for the . Since you will be computing manually, review the answer choices and eliminate the unlikely answers. 396 is definitely not the answer because the square root of 396.25 will be a much smaller number. 40 is also out because if you square it,
18 is also eliminated because .
Checking out 20, it is the best answer because , very close to 396.25.
Where do lines y = x - 1 and y = -5x + 11 intersect?
In parallelogram ABCD, ∠ = 4x + 8 and ???? = 6x - 10. Find the measure of ∠.
Austin, Texas has a statue of Stevie Ray Vaughn that is 12 ft tall. It casts an 8 ft shadow. Doug stops to admire the statue. Doug's shadow is 3.5 ft.
How tall is Doug?
If Hunter scored an average of 76 on his first four tests, what is the minimum he must score on his fifth test in order to have an overall average of 80?
Next, you will need to find the total of what you want. There are 5 tests, and you want an average of 80. Multiplying 5 by 80 gives you a total of 400.
Then, you will need to find the difference between the totals on the first 4 tests and all 5 tests. Subtracting 304 from 400 gives you a total of 96.
Meghan raised funds for the Cancer Society for seven straight days. She raised the following amounts:
$525, $350, $275, $630, $1,010, $275, and x.
What would the value of x equal if the average funds collected were $500?
($525 + $350 + $275 + $630 + $1,010 + $275 + x) × 7 = $500.
Solve for x.
($3,065 + x) × 7 = $500
$3,065 + x = 7 × $500 = $3,500
x = $3,500 - $3,065 = $435
A bus arrives at the bus station every 2 hours, a second bus arrives every 3 hours, and a third bus arrives every 4 hours.
If all 3 buses arrive at 9:00 AM, at what time will all 3 buses next arrive at the same time?
Solve the following equation:
|2x + 6 - 5x| = 9
x = 1 or x = 5
x = -1 or x = 5
x = -3 or x = -5
x = 3 or x = 5
John adopted his dog exactly 5 years and 12 days ago. At this instant, how many minutes has John had his dog? (Ignore leap years.)
Which of the following pairs of points both lie on the line whose equation is 4x-2y= 10?
(3,2) and (4,4)
(8,3) and (6,-1)
(2,-2) and (5,5)
(3,1) and (6,7)
|3 + x| = 5
Which of the following options is the correct solution set for the above equation?
Kyle borrows $12,000 for a period of five years to buy a used car.
