Find the point of intersection of lines L: x = 7 and M: y = -8.

What is the equation of this line in slope-intercept form?  5x + 2y = -7

Does the point (1, 20) satisfy the following system of equations?
y = -2x + 15
y = x +12

What is the slope of a line parallel to a vertical line?

Find the equation of the line, in slope-intercept form, passing through the points (2,4) and (5,13).

Write an equation of the line containing the point (8,-4),
and parallel to the line 4x - 9y = 5.
