Question

Write an equation in slope-intercept form(7,2), (2,12)

Answer 1

Aliyah, this is the solution:

Let's calculate the slope, as follows:

(12 - 2)/(2 - 7) = 10/-5 = -2

Now, let's write the slope-intercept equation, this way:

y = mx + b

We already know that m = -2, now let's calculate b:

12 = -2 (2) + b

12 + 4 = b

b = 16

Therefore,

y = -2x + 16
