Question

Write the equation of a line in slope intercept form that has a slope of -2 and passes through the point (5,11).

Answer 1

y = -2x + 21

Explanation:

use point intercept form: y = mx + b where m is the slope and b is the y intercept

to find the y intercept, b, plug in values into equation and solve for b

11 = (-2) (5) + b

b = 21

then plug into the equation the slope and intercept!
