Question

Find the y-intercept of a line that passes trough (-7,9) and has a slope of 3

Answer 1

(0,30)

Explanation:

y=mx+b

9=3(-7)+b

9=-21+b

30=b

y-intercept (0,30)

Answer 2

y = 3x + 30

Explanation:

Slope intercept form [ y = mx + b ] where m = slope and b = y-intercept.

Solve for the y-intercept with the gaven variables.

y = 3x + b

9 = 3(-7) + b

9 = -21 + b

30 = b

y = 3x + 30

Best of Luck!
