Peter is an artist, and he charges for his paintings on an hourly basis. He also receives tips from many of his clients. The scatter plot below shows the number of hours Peter
worked on a painting and the amount of money he received from his client. A line of
best fit for these data points, the equation y=85x+20, is also shown on the plot.

On average, how many more dollars does a client pay for a painting that takes 4 hours
than a painting that takes 3 hours?

good luck!

cutie~

just find the gcf and solve the gcf's until you get each answer i have a really good feeling somethings missing xd (like the dimensions of the fence) *cough *cough *hint *hint

step-by-step explanation:

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
