Question

What is the value of k if a line passes through (6,3) and (2,k) has a slope of -1?

Answer 1

Answer:

k = 7

Step-by-step explanation:

Slope = $\frac{rise}{run}$

-1 = $\frac{k-3}{2-6}$

Multiplying both sides by 2-6

-1(2-6) = k-3

-1(-4) = k-3

4 = k-3

Adding 3 to both sides

k = 4+3

k = 7
