-7x - 3y = 42, let y = 0 and replace 0 for y into the equation
-7x - 3(0) = 42
-7x = 42, divide by -7 to both sides
x = -6
so the x-intercept is -6, or the x-intercept point is (-6, 0).

Slope is -1 y-intercept is 1 x-intercept is 1
y intercept 7 x intercept 7/3
-x -2y = 6At the x-intercept, y = 0.-x = 6x = -6
x + 2y = 10At the x-intercept, y=0:x = 10At the y-intercept, x=0 ==> 2y = 10y = 5
42 x 42 = 1764 42 + 42 = 84
