Question

Find the value of x or y so that the line through the points has the given slope (x, -7) and (3, 3); slope:1

Answer 1

Answer:

The answer is x = -7.

Step-by-step explanation:

In order to find this, we need to start by using the slope formula with all of the information that we have.

m(slope) = (y2 - y1)/(x2 - x1)

1 = (3 - -7)/(3 - x)

1 = 10/(3 - x)

Now we can use cross multiplication to solve for x.

1(3 -x) = 1(10)

3 - x = 10

-x = 7

x = -7
