Question

Write an equation in slope intercept of a line parallel to x=5 and passes through point (4,-3)

Answer 1

Slope-intercept form is y=mx+b where m is the slope. Parallel lines have the same slope.
y = 5x + b
"b" is the y-intercept. The y-intercept is when the x-coordinate is 0. So to solve for the y-coordinate you can use the slope formula and the known info.
Solve for b. :)
