What is the equation of the line that passes through (4,6) and (4,-4)

The slope is undefined, no equation

Step-by-step explanation:

Use the given points to solve for the slope.

The slope is undefined because a number cannot be divided by 0.

This means that the line is a vertical line at the x-intercept, and an equation cannot be found because we need a slope to solve the point-slope formula.

The line is at 4 on the x-axis because that is the number given for the x in each point.

y -y = m(x - x)

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
