Maybe u should do inverse operation on both sides idk but just try it
Answer:
y = -4x + 60
Step-by-step explanation:
(0, 60) and (4,44)
Slope:
m=(y2-y1)/(x2-x1)
m=(44 - 60)/(4-0)
m= (-16)/4
m= -4
Slope-intercept:
y - y1 = m(x - x1)
y - 60 = -4(x - 0)
y - 60 = -4x
y = -4x + 60
30% is 24
45% is 36
take 15% and multiply it by however much it takes to make the percentage than multiply that by 12
