Match each of the following equations according to their slope and y-intercept.
y = 1.5x - 7
m = -1.5, b = -4
y = -1.5x - 4
m
= 3, b=0
y = -3x + 4
m= -3, b = 4
y = 3x
m
= 1.5, b = -7
y = 7
m = 0,b= 7
Intro

Slope-intercept form:  y = mx + b

(m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis)

y = 1.5x - 7            m = 1.5     b = -7

(y = (1.5)x + (-7) > y = 1.5x - 7)

y = -1.5x - 4         m = -1.5      b = -4

y = -3x + 4           m = -3       b = 4

y = 3x          m = 3        b = 0

y = 7        m = 0     b = 7

(y = (0)x + 7  ---> y = 7)
