Select the eqaution that passes through the point (1,-1) and has a slope of 4 (a. y+1=4x-1) (b. y-1=4x+1) c y-1=(x+1) and d y+1=4(x-1)

Step-by-step explanation:

y - y1 = m(x - x1)

(1,-1)x1 = 1 and y1 = -1

slope(m) = 4

now sub

y - (-1) = 4(x - 1) =

y + 1 = 4(x - 1) <

could you reply to this with the question so i can ?

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
