With #2 pls and show me how with work

Remember
you can do ANYTHING to an equation as long as you do it to BOTH SIDES
also
a/a=1
ab/ab=1

so
we want to solve for h or 1h

T=pirh
divide both sides by pir (since pir/pir=1)
T/(pir)=1h
T/(pir)=h

Ai just took the test

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
