5-16.

Write the equation of each line described below. Homework Help ✎

1. A line with slope –2 and y-intercept 7

Remember that Slope-Intercept form is y = mx + b..

2. A line with slope $- \frac { 3 } { 2 }$ and x-intercept (4, 0).

• $\text{Substitute }-\frac{3}{2}\text{ for }m\text{ in }y=mx+b$

• Substitute 4 for x and 0 for y.

• 0 = −6 + b

• Solve for b.

• b = 6

• $\textit{y}=-\frac{3}{2}\textit{x}+6$
