A line includes the points (-3, 8)and (-1, 2). What is its equation in slope- intercept form

Natasha_Volkova [10]

Solve for slope first:
m = $\frac{y2 - y1}{x2 - x1}$

m = $\frac{2-8}{-1-(-3)}$ = -3

then solve for b in y = mx + b

8 = -3(-3) + b
b = -1

y = -3x - 1

What is the y-intercept of the line y+11= -2(x+5)?

poizon [28]

Answer:

y-intercept is (0, -21)

Step-by-step explanation:

For y-intercept, x = 0:

${ \sf{y + 11 = - 2(0 + 5)}} \\ { \sf{y + 11 = - 10}} \\ { \sf{y = - 21}}$
