Hello!
The equation for slope intercept form is y = mx + b, where m is the slope and b is the y intercept.
We can first find the slope. Perpendicular lines have slopes which are negative reciprocals of each other. This means that the slope of the line you're looking for would be the negative reciprocal of -2/9. The negative reciprocal of -2/9 is 9/2. Therefore, m = 9/2.
Substitute this into the equation. y = 9/2x + b. Now substitute in the point given and solve for b.
y = -4, x = -2
-4 = 9/2 (-2) + b
-4 = -9 + b
b = 5
Therefore, the final equation is y = 9/2x + 5.
Hope this helps!

First I foiled. This meaning that I multiplied the first numbers in each pair of parentheses, then I multiplied the outside numbers, then the inside numbers and finally the last numbers.
p^2-p-56
Second I combined like factors.
This should be your final answer, keep in mind that ^2 means squared.
p^2-p-56
