Find the equation of the line with slope -1/2 and passing through (3,-1)

y=-1/2+5/2

Step-by-step explanation:

1. use point slope formula:

y-y1 = m(x-x1)

2. plug in values

y-(-1)=-1/2(x-3)

3. solve into y intercept form (y=mx+b)

y-1=-1/2x+3/2

y=-1/2+5/2

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
