Does the graph represent a function? y 97 8 7+ 6+ 5+ 3 M - 7 -6 -5 -4 -3 -2 1 2 3 4 5 6 7 -2+ -3+ -4 -5 Choose 1 A Yes B No

Yes

Step-by-step explanation:

A function is a relation where each x value has its own y value.

If a x value repeats the relation is not a function

Looking at the graph, no x value repeats therefore the graph is indeed a function

a

step-by-step explanation:

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
