The graph shows the numbers of quarts of yellow paint that must be mixed with different numbers of
quarts of red paint to make a certain shade of orange
paint.

Step-by-step explanation:

The given graph is a straight line graph. The y axis represents the number of quarts of yellow paint that is mixed. The x axis represents the number of quarts of red paint that is mixed. We would write the required equation in the slope intercept form. The slope intercept form equation of a straight line is expressed as

y = mx + c

Where

m represents slope

c represents y intercept.

Slope = (y2 - y1)/(x2 - x1)

Slope = (2 - 1)/(5 - 2.5) = 1/2.5

Slope = 0.4

The straight line cuts the y axis at y = 0

It means that c = 0

Therefore, the equation is

y = 0.4x

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
