Can someone help me with this??

Step-by-step explanation:

m = 1/2

Point = (1,4)

General formula

y = mx + b

y = 1/2 x + b

x = 1

y = 4

4 = 1/2 (1) + b

4 = 1/2 + b              Subtract 1/2 from both sides

4 - 1/2 = b

b = 3.4

y = 1/2 x + 3.5

a - base

b - exponent

so,

u = -(6/7)w

step-by-step explanation:

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
