Question

What is the slope-intercept form of the line that passes through the points (-2,-3) and (1,9) ?

y=1/4x-2 1/2
y=1/4x-3
y=4x+5
y=4x−3

Answer 1

y = 4x + 5

Explanation:

Slope formula: y2 - y1 / x2 - x1

9 - (-3) / 1 - ( -2)

12 / 3 = 4

m = 4

y-intercept (b)

y = 4x + b

9 = 4(1) + b

9 = 4 + b

b = 5

Slope-intercept formula: y = mx + b

y = 4x + 5

Answer 2

y=4x+5
