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

Answer:

b = 8

Step-by-step explanation:

Use the Pythagorean theorem

c^2 = a^2 + b^2

c = 10

a = 6

b = ?

Substitute into the formula

10^2 = 6^2 + b^2

100 = 36 + b^2 Subtract 36 from both sides

100 - 36 = b^2 Combine

64 = b^2 Take the square root of both sides.

√64 = √b^2

b = 8
