5y = 15x -45
Divide by 5
y = 15x/5 -45/5
y = 3x -9
y = mx + b
m= 3
6 = -9
The slope is 3
The y intercept is -9

In slope intercept form, m IS the slope. y = mx + b slope is change in height divided by change in x direction.
Slope intercept is an equation of the form y=mx+b where m is the slope and b is the y-intercept.
y= slope + y-intercept
The slope intercept form is y=mx+b where m is the slope and b is the y intercept y=2x-8.
y=mx+b is the slope intercept equation m=slope b= y-intercept y=-7x + 2 m= -7 b= +2
