The equations will be y-b/ x =m/1, y-b=m(x) and y=mx +b
Step-by-step explanation:
In the diagram you can show the two triangles are similar by showing that the ratio of rise to rum is equal.This is
y-b/ x =m/1 Multiplying both sides by x y-b=m(x) Adding b on both sides will eliminate the b on the left side as; y-b+b= mx+b y=mx +b where m is the slope and b is the y-intercept
