if the ordered pair (x,y) is (-3, 4), then the othre ordered pair would (0,0)
Then, you find the slope(m).
So, m = y2 - y1
x2 - x1
if y2 is 4 and y1 is 0
x2 is -3 and y1 is 0
now you subtract to get -4
3
So, m= -4

Then, find the y-intercept
So, y=mx+b and substitute the ordered pair (0,0) into y= mx+b
y=mx+ b
0= -4(0) +b
3
0=0+b
-0 -0
b=0
So the equation is y= -4x
