step-by-step explanation:
y = | -2(-2) | → y = | 4 | → y = 4 ⇒ (-2, 4)
y = | -2(-1) | → y = | 2 | → y = 2 ⇒ (-1, 2)
y = | -2(0) | → y = | 0 | → y = 0 ⇒ (0, 0)
y = | -2(1) | c → y = | -2 | → y = 2 ⇒ (1, 2)
y = | -2(2) | → y = | - 4 | → y = 4 ⇒ (2, 4)
u = -(6/7)w
place all values with 'u' on one side of the equation.
4u + 8w = - 3u + 2w
4u + 3u = 2w - 8w
further simplify the equation by solving the addition and subtraction.
7u = - 6w
make 'u' the independent variable by placing its co-efficient on the right-hand side.
u = - (6/7)w
8+10
you multiply 4 by 2 and 5 by 2
