Answer:
the desired equation is y = 2x - 3
Explanation:
Parallel lines have the same slope. Thus, a new line parallel to y = 2x - 4 has the slope 2.
Find the equation of the new line by writing out the slope-intercept form
y = mx + b. Substitute -1 for y and 1 for x:
-1 = 2(1) + b, which yields b = -3
Then the desired equation is y = 2x - 3
