To graph a line, it is helpful to have two points. You can plug any number in the equation for x and number crunch to solve for its corresponding y value. Do that for a second value of x, and you’ll get a second value of y. plot those points on a graph and draw a straight through them.

for example,

y=-3x+4

set x=0, then y=4, so one point on the line is (0,4)

set x=1, then y=1, so another point is (1,1)

draw your line THROUGH both points

5x-2y=10x

what is y when x=0? y=0 or (0,0)

what is y when x=2? y=-5 or (2,-5)

not sure what you meant by

=4y and

=-2
