Answer:
-7 is -7 units away from zero. Its opposite is 7 from zero.
Step-by-step explanation: Count from 0 how many digits away it is
The slope is 7. whatever number is next to x is the slope. if there is no x then it is a horizontal or vertical line.
SA=2pir^2+2hpir=2pir(r+h)
h=2r=2(2x+3)=4x+6
SA=2pi(2x+3)(2x+3+4x+6)
SA=(4x+6)(pi)(6x+9)
SA=24πx²+27πx+54π
So basically, the 2 is the y- intercept which means that is where your line starts. The 1/2 is the slope which means you make a dot every time you go up 1 and over 2
