Question

Use an equation to find the value of k so that the line that passes through (-2,k) and (2,0) has a slope of m=-1

Answer 1

The value of k is 4.

Explanation:

To find the missing coordinate, we can use the slope equation and plug in all known values.

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

-1 = (k - 0)/(-2 - 2)

-1 = k/-4

Now we can solve using cross multiplication.

-1 = k/-4

k*1 = -1*-4

k = 4
