Find the slope m.
Use the point-slope formula.
Solve for y.
Answer:
y=-1/2x+3/2
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-1-1)/(5-1)
m=-2/4
m=-1/2
y-y1=m(x-x1)
y-1=-1/2(x-1)
y=-1/2x+1/2+1
y=-1/2x+1/2+2/2
y=-1/2x+3/2
You would multiply 2 1/2 and 3 3/4, which would give you 9.375 or as a mixed number 9 7/8
