Hope this helps! Don't flip the sign at the end when you divide because it's a positive number being divided. Only flip when it's a negative number. Any questions comment!
I am not for sure but I think 1.13*10-4
First, we calculate the slope of the line using:
slope = (y₂ - y₁)/(x₂ - x₁)
= (4 - (-5)) / (-5 - (-7))
= 9/2
Point slope form:
y - y₁ = m(x - x₁)
y + 5 = 9/2 x (x + 7)
Simplifying to standard form:
2y + 10 = 9x + 63
-9x + 2y = 53
Thus, the answer is C
