Answer:
3
Step-by-step explanation:
We can find the slope using the equation y2-y1/x2-x1=m. So first, we want to subtract 1 from 10, which is 9.
Then, we subtract -2 from 1, which turns into 1+2, or 3. Then divide 9 by 3, which is 3. The slope is 3.
Hope this helps!
Hello!
In order to find J you must multiply 6 by seven because J is 7 times larger than 6. So : 7 ⋅ 6= 42.
I hope it helps!

now, this parabolic graph, has two zeros/solutions/x-intercepts, at -9 and 21.
for a quadratic equation, the vertex will be right in between the x-intercepts, namely in this case between -9 and 21, right in the middle, namely at 6, and is where the axis of symmetry is at, x = 6.
