Exercise 1 Page 78

Apply inverse operations to isolate y.

y=1/2x+1

Practice makes perfect
Rewriting any linear equation in the slope-intercept form requires us to isolate the y-variable. To do this, we will use the Properties of Equality to apply inverse operations on the equation.
x-2y+3=1
x+3=1+2y
x+2=2y
x+2/2=y
x/2+2/2=y
x/2+1=y
1/2x+1=y
y=1/2x+1
