#2:Tell whether the equation, 8y + 3 = 5x + 3, is a direct variation. If it is, find the constant of variation. (Show your work!)

Multiple choice #3:What is the slope and y-intercept of the graph of the equation y = 2x + 3?
A:slope = 1/2 y-intercept = 3
B:slope = 3 y-intercept = 2
C:slope = 2 y-intercept = 3
D:slope = 1/3 y-intercept = 2

Answer 1

Simple...

you have: 

1.) Find the slope of the line using (-2,1) and (3,6)

Using $\frac{ y_{1}- y_{2} }{ x_{1} - x_{2} }$

$\frac{1-6}{-2-3} = \frac{-5}{-5}$

m=1 (slope)

2.)Tell whether the equation, 8y+3=5x+3, is a direct variation.

y=$\frac{5x}{8}$ (None)

3.)What is the slope and y-intercept of the graph of the equation y=2x+3?

Slope =2 

y-intercept=3

C.

Thus, your answer.
