Step-by-step explanation:
Im not doing the answer but here is a super awesome way to figure it out with tens. and since you ave a computer just use calculator. if the exponent is over a ten, its literally telling u how many zeros to put so if I have 10^5 I put 5 zeros behind it. So just do that in a calculator to get the values and then its as simple as a 3rd grade question
Y=3x + 5
Y=mx + b
(m is the slope or gradient and b is the y intercept)
A right triangle must have a 90 degree angle
