Question 849777: Please help me figure out if y=4x+12 and -4x+3y=21 are parallel on a graph chart

The first one is in slope intercept form. The slope is 4.
The second one is in standard form, and some of what you learn about this form for a line is that ..., in this example's case, 4/3 is the slope.
Lines in the plane are parallel if their slopes are equal.
