First let’s find the slope of the line given. m=y2-y1/x2-x1 m=6-3/-4-(-3)= -3 Now y=mx+b is equation of a line. We just found m so let’s plug in two points from the graph for our (x,y) values
6=-3(-4)+b Therefore b = -6. So our line equation is y=-3x-6
So now we can find the coordinate point for the y-intercept which is (0,-6)
Hope this helps explain the concept! Any questions please ask!! Thank you!!
