Drag equations to each row to show why the equation of a straight line is y = mx + b, where m is the slope and b is the y-intercept.

The equations will be y-b/ x =m/1, y-b=m(x) and y=mx +bStep-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  Learn More  To write the slope-intercept equation :  The slope intercept equation :  Keywords : slope intercept equation  #LearnwithBrainly
