#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
`( y_(1)- y_(2) )/( x_(1) - x_(2) )`


`(1-6)/(-2-3) = (-5)/(-5)`

m=1 (slope)

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

y=
`(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.
