A line passes through (1,5) and (-2,-1).Find the slope-intercept form of the equation of the line.Then fill in the value of the slope, m, and the value of the y-intercept, b, below

Respuesta :

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

(-2,-1) 1 - (-2) = 3


y = 3x + b

5 = 3 + b

b = 2

y = 3x + 2


slope = 3 = m

y-intercept = 2 = b

y = 3x + 2
