Using the point-slope formula, what is the equation of the line that passes through the points (1, 5) and (0, 0)?
a. y = 5x – 1
b. y = 5x
c. y = x
d. y = 5x + 10

answer:   y=2x-3

step-by-step explanation:

left be aligning the decimal points is required to not required see the number of digits to the right

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
