Write the equation of the line in slope-intercept form that passes through the two points. (15, 1) and (0, - 4)

y=1/3x-4

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-4-1)/(0-15)=-5/-15=1/3

y-y1=m(x-x1)

y-1=1/3(x-15)

y=1/3x-15/3+1

y=1/3x-5+1

y=1/3x-4

y=mx+b

step-by-step explanation:

m slope

b y-intercept

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
