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.

y-b/x= m/1 Triangle 1 is similar to triangle 2

y-b=mx  Multiply both sides by x.

y=mx+b Add b to both sides.

step-by-step explanation:

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
