3. Use the slope-intercept form
y=mx+b to find the slope m and y-intercept b.
Slope: 1/3
Y-Intercept: 9/4
4. 2(3x−9)=5x+2
Step 1: Simplify both sides of the equation.
2(3x−9)=5x+2
(2)(3x)+(2)(−9)=5x+2(Distribute)
6x+−18=5x+2
6x−18=5x+2
Step 2: Subtract 5x from both sides.
6x−18−5x=5x+2−5x
x−18=2
Step 3: Add 18 to both sides.
x−18+18=2+18
x=20
