I think you're right. I'm in pre-algebra, and sucks at it. Yet, I keep a A.
Answer:
y=-2x
Step-by-step explanation:
Because, let us take (-1,2)
2=-2(-1)
2=2
Similarly all the points show the same.
Based on the docx you showed me, the equation for the parabola is
and you want a table of values for a linear equation that intersects the parabola at (5, 6) and (-2, 34).
If you use these two points to create a line we get the equation:
(I just used point slope form)
This can be simplified to:
Now we just need to create a table of points on this line. We already have the points you gave and we can also use the y-intercept:
and the x-intercept:
.
So our table of value can be:
x | y
______|________
-2 | 34
0 | 242 / 7
5 | 6
121/20 | 0
