A line passes through the point (-2,9) and has a slope of 7

y = 7x + 23

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 7, thus

y = 7x + c ← is the partial equation

To find c substitute (- 2, 9) into the partial equation

9 = - 14 + c ⇒ c = 9 + 14 = 23

y = 7x + 23 ← equation of line

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.
