9x-10y = -90
For this case what you should do is see the intersections with each of the axes and then join the ordered pairs.
We have then:
For the x axis:
y = 0
Substituting in the equation:
9x-10 (0) = - 90
9x-0 = -90
x = -10
For the y axis:
x = 0
Substituting in the equation:
9 (0) -10y = -90
0-10y = -90
y = 90/10
y = 9
We graph the ordered pairs:
(x1, y1) = (- 10, 0)
(x2, y2) = (0, 9)
Answer:
See attached graph.
