How do you calculate
A=210(0.5)^2/5.7

First you do the exponent

210 * 0.5² / 5.7

= 210 * 0.25 / 5.7

Then multiplication and division

= 52.5 / 5.7

≈9.2

i think ur answer is   (3,-1)

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
