Find the graph of y=-3/4X-2
morpeh [17]
To graph the line y=- \frac{3}{4}x-2 we are going to take advantage of the fact that its y-intercept is -2 when x=0, so our first point is (0,-2). To find our second point, we are going to find the x-intercept; to do it, we are going to set y=0 and solve for x:
y=- \frac{3}{4}x-2
0=- \frac{3}{4}x-2
2=- \frac{3}{4}x
x= \frac{2}{- \frac{3}{4} }
x=- \frac{8}{3}
Now that we have our second point (0,- \frac{8}{3} ), we just need to join our two points with a straight line.

We can conclude that the graph of <span>y=-3/4X-2 is:</span>
