Slope is -3

Equation is y = -3x + 2

Step-by-step explanation:

(0 , 2) and ( -1 , 5)

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

m= (5 - 2)/(-1 -0)

m= 3/-1

m= -3

y - y1 = m(x - x1)

y - 2 = -3(x - 0)

y - 2 = -3x + 0

y = -3x + 2

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
