<u>Step 1: Define</u>
x³ + 3x² = x + 3
x = -1
<u>Step 2: Check</u>
- Substitute in <em>x</em>: (-1)³ + 3(-1)² = -1 + 3
- Evaluate exponents: -1 + 3(1) = -1 + 3
- Multiply: -1 + 3 = -1 + 3
- Add: 2 = 2

Answer:
y = 2x +13
Step-by-step explanation:
when 2 lines are perpendicular, the product of the two gradients is -1
i.e. m x m1 = -1
so from 10y + 5x = 3, the gradient m is -0.5
m1 = -1 / -0.5 = 2
using m1 = 2 and pt(-7,-1),
the eqn is y = (m1)x +c
-1 = 2(-7) + c
c= 13
thus y = 2x +13
