(-5, 2) ⇒ x₁ = -5, y₁ = 2
(7, -1) ⇒ x₂ = 7, y₂ = -1
Slope:
![\bold{m=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{-1-2}{7+5}=\dfrac{-3}{12}=-\dfrac14}](https://tex.z-dn.net/?f=%5Cbold%7Bm%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%3D%5Cdfrac%7B-1-2%7D%7B7%2B5%7D%3D%5Cdfrac%7B-3%7D%7B12%7D%3D-%5Cdfrac14%7D)
Slope intercept form:
y = mx + b
Plug <em>m</em> and (7, -1) :
-1 = -¹/₄(7) + b
-1 + ⁷/₄ = b
<h3>b = ³/₄ ← y-intercept</h3>
Therefore slope intercept form of h(x):
<h3>h(x) = -¹/₄x + ³/₄</h3>

I was wondering the same thing. maybe it is specific for certain people.
Step-by-step explanation:
Answer:
x-7>0
Straight answer: x-7
Step-by-step explanation:
Assuming that the timber is X cm long and 7cm was cut off, there remaining amount is x - 7cm. In order for 7cm to be cut off, the timber must have been > 7cm long => x > 7 => x - 7 > 0
