Write the equation that satisfies the given conditions. The line passes through the two points (3, -1) and (-2, 5). Choices A. 5

rodikova [14]

(3,-1)(-2,5)
slope = (5 - (-1) / (-2 - 3) = -6/5

y = mx + b
slope(m) = -6/5
(3,-1)...x = 3 and y = -1
sub and find b, the y int
-1 = -6/5(3) + b
-1 = -18/5 + b
-1 + 18/5 = b
-5/5 + 18/5 = b
13/5 = b

so ur equation is : y = -6/5x + 13/5
