Question

Use the given information to write an equation of each line.
14. Slope -5, y-intercept -2
16. Passes through (1,5) and (3,11)

Answer 1

14. slope intercept form y-y1=m(x-x1)
y-2=-5(x-0)
y=5x+2



16.
$slope (m)= \frac{y2 - y1}{x2 - x1} \\ = \frac{11 - 5}{3 - 1} \\ = \frac{6}{2} \\ = 3 \\ equation \: is \: \\ y - y1 = m(x - x1) \\ y - 5 = 3(x - 1) \\ y - 5 = 3x - 3 \\ y = 3x - 3 + 5 \\ y = 3x + 2$
