Write an equation of the line that passes through the points.
(0,-2) (4,-2)

y = -2

Since this is a line, it will be a straight linear line passing. Since it passes through coordinates with same y value, there is no slope.

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925

or

step-by-step explanation:

we need to solve for 'x' the following equation:
