Question

Which equation in slope-intercept form represents a line that passes through the point (5,−1) and is parallel to the line y=2x−7?
y=2x−11
y=−9x−7
y=2x−9
y=−12x−7
y=−11x−7
B?

Answer 1

parallel lines have the same slope...so the x-coefficients have to be the same

use the given point to test the two that have the right slope (x-coefficient)

Answer 2

just to clarify, the slope must be 2. Now you have apoint and a slope, so start with the point-slope form of the line:

y+1 = 2(x-5)
Now see which choice matches that when rearranged to slope-intercept form.

Answer 3

(5, -1)
Y = mx+b
-1 = 2*5+b
b = -11.

Y = 2x-11.
