the equation of the straight line that passes through the point with coordinates of 0,0 and 2,8. do the same for the coordinates of 0,0 and 4,20,0 and 2,10

Equation of a line passes through (0,0) and (2,8):

Equation of a line passes through (0,0) and (4,2):

Equation of a line passes through (0,0) and (2,10):

Step-by-step explanation:

Equation of a line passes through (a,b) and (c,d) :

Then, Equation of a line passes through (0,0) and (2,8):

Equation of a line passes through (0,0) and (4,2):

Equation of a line passes through (0,0) and (2,10):

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
