3. Identify the correct x intercept and y intercept of the equation 4x – 3y = 24. (4 points)
x intercept = (6, 0); y intercept = (0, –8)
x intercept = (–6, 0); y intercept = (0, 8)
x intercept = (–8, 0); y intercept = (0, –6)
x intercept = (8, 0); y intercept = (0, 6)

Answer 1

1. The formula for slope is: m = y2 - y1/ x2 - x1
if we plug it in, we get m = 2 - 5/ 5 - 1 which is -3/4 and there's your slope:)

2. Using the formula for slope as I showed you in the first question: m = y2 - y1/ x2 - x1
if we plug it in, we get m= 4-3/8-(-2) which is 1/10 and there's the slope :D

3. For this one, you can either plug them in (since it's multiple choice) or you can solve it as it is.

start by solving for y
4x – 3y = 24
subtract 4x from each side to get:
-3y = 24 - 4x
divide each side by -3 to get:
y = -8 + 4/3x
OR
y = 4/3x - 8

and there is your slope (4/3x), and y-intercept(-8).

and now if you look above in the choices they gave you to choose from, find the one with the y-intercept of -8, which is "x intercept = (6, 0); y intercept = (0, –8)" :)

hope i helped!

Answer 2

um. did you get it? (or ...)
