Question

What does the line -4x + 3y = -7 look like?

Answer 1

there are a few ways to find out.

one way is find two points on the line, plot the two points, and draw a line through those points.

to find a point, let x=0 in the equation
-4*0 + 3y= -7
and solve for y. we get y = -7/3 = -2 ⅓

another point: let y=0 and solve for x
-4x +3*0 = -7
-4x = -7
x= -7/(-4) = 7/4 = 1 ¾

plot (0, -2 ⅓) and (1 ¾ , 0)
