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-interc
2 answers:
Answer:
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.
Answer:
m is the slope because it is affected by the value of x. They are multiplied together and therefore are affected by one another.
The b is the intercept because even when the x value is 0, the value of the y-intercept exists.

Find the reciprocal of 4 and multiply.
Multiply the numerators and denominators together:
Answer:
I believe the answer is y = -8
I believe that it is A=r(pi)*2
Ok so first we do 2 + 3 = 5 * 2 = 10 / by 42 = 4.2
other side 36 - 52 = 16 * 4 = 64 now add 4.2 + 64 = 68.2
