Apainter mixes 2 1/2 pints of yellow paint with 4 pints of red paint to make a certain shade of orange paint. how many pints of yellow paint should be mixed with 10 pints of red paint to make this shade of orange?

For every 4 pints of red, there are 2 1/12 pints of yellow. 8 of those red pints would make 5 yellow pints. Adding 2 more pints of red to get to the 10 would mean you have to half the 2 1/2, which would be 1 1/2. So, you would need 6 1/2 pints of yellow mixed with the 10 red pints to make the shade of orange. :)

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
