Question

What is the y-intercept of the line passing though the point (9,-7) with a slope of -1/8

Answer 1

y-intercept (0, -47/8)

Explanation:

Point slope equation form:

y + 7 = -1/8(x - 9)

y + 7 = -1/8 x + 9/8

y = -1/8 x + 9/8 - 56/8

y = -1/8 x - 47/8

y = mx + b where m=slope and b = y intercept

In this case, y intercept = -47/8

Answer:

y-intercept (0, -47/8)
