Slope=y2-y1/x2-x1
Slope=1.2-0/2-0
Slope= 0.6
This is pretty much saying that if x = -3, then solve for the equation, so (-3)^2 - 4(-3) = 9 - 12 = -3
We can use tangent to calculate the length of ST.

Here, the opposite side of the 60 degree angle is ST, and the adjacent is RS. Plug in what we know, we can use 'x' for side ST:

Solve for 'x', multiply 7 to both sides of the equation:

This is an exact answer for the length of ST, we can find an approximate with a calculator:
Answer:
<em>(0, 2)</em>
Step-by-step explanation:
Function is the relation where each value of "x" has single value of "y"
The table contains pair (0, - 2) if table would include (0, 2) the relation in table would be not a function.
