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

<span>If a spinner has 9 equally-sized slices, then there is an equal chance of the spinner landing on any one of those slides. If, as in this case, there are 7 white slices and 2 black slices, then the chance of the spinner landing on a black slice is 2/9. And, to answer the question, the odds of landing on a white slice are therefore 7/9, or about 78%.</span>
It'll feed 60 birds because 1 ounce feed 5 bird and if you multiply 12 by 5 you'll get 60
The sum of the equation is 5
