Question 548901
9x -4y = 36
.
Get the above into slope-intercept form:  y = m*x + b
.
-4y = -9x +36
y = 9/4*x -9
.
9/4 = slope
(0,-9) = y-intercept
.
To find the x-intercept, set y = 0 and solve for x.
.
0 = 9/4*x -9
-9/4*x = -9
cross multiply
-9*x = -9*4
-9*x = -36
x = 4
which defines the x-intercept:  (4,0)
.
With two points, you can draw a line.
