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

y-intercept (0, -47/8)

Step-by-step 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

y-intercept (0, -47/8)

x=-5 or x=3

Step-by-step explanation:

when multiplying anything by 0, the answer will be zero

In this case, one of the two factors has to be equal to 0

start by splitting into

(x+5) = 0

solve the equation

subtract 5 from both sides

x = -5

now, repeat for the other binomial

x-3 = 0

add 3 to both sides

x=3
