What are the x-intercept and the y-intercept of the graph of 9x - 7y = -63?
+128475 9x - 7y = - 63
To get the slope, isolate y
-7y = - 9x - 63 divide both sides by -7
y = (9/7)x + 9 the slope is 9/7
y intercept.....let x = 0
9(0) - 7y = - 63
-7y = - 63 divide both sides by -7
y = 9
x intercept.....let y = 0
9x - 7(0) = -63
9x = -63 divide both sides by 9
x = -7

+636 Slope = 2.571/2.000 = 1.286
x-intercept = 14/9 = 1.55556
y-intercept = 14/-7 = 2/-1 = -2.00000
+128475 9x - 7y = - 63
To get the slope, isolate y
-7y = - 9x - 63 divide both sides by -7
y = (9/7)x + 9 the slope is 9/7
y intercept.....let x = 0
9(0) - 7y = - 63
-7y = - 63 divide both sides by -7
y = 9
x intercept.....let y = 0
9x - 7(0) = -63
9x = -63 divide both sides by 9
x = -7
