Y=1 1/4(1.25)x +9, add 8x to each side and then divide each side by 6
Answer:
5 : 8
Step-by-step explanation:
20 : 32
divide both ratios by 4
5 : 8
So remember that paralell lines have the same slope
y=1/4x-6
1/4=slope
so we set up a new equation in slope intercept form
y=mx+b
m=slope
b=y-intercept
y=1/4x+b
one solution si (-1,5) where x=-1 and y=5
subsitute
5=1/4(-1)+b
5=-1/4+b
add 1/4 to both sides
5+1/4=21/4=b
the answer is y=1/4x+21/4
So 29-4 =25... which is a perfect square
Answer= +/- 5
