Question

What is an equation of the line that passes through the points (2, -6)(2,−6) and (-1, 6)(−1,6)?

Answer 1

y = -4x + 2

Explanation:

To figure out the slope, plug the coordinates in the formula.

y2 - y1 / x2 - x1

= 6 - (-6) / -1 -2

= -4

Now you need to find the y-intercept, take the coordinates and plug them into your equation so far, which is y = -4x + b

y = -4x + b

-6 = -4(2) +b

-6 = -8 + b

2 = b
