If the equation is passing trough the origin, it will be passing trough the point (0,0). We now for our problem that the equations is also passing trough the point (-4,3). So, our line is passing trough the points (0,0) and (-4,3). To write the equation in slope-intercept form, first, we need to find its slope . To do that we are going to use the slope formula: .

From our two points we can infer that , , , . Lets replace those values in the slope formula:

Now that we have our slope, we can use the slope-intercept formula:

We can conclude that the equation of the line passing trough the points (0,0) and (-4,3) is .

3xc = -5, solve for x

atroni [7]

Answer:

$x = -\dfrac{5}{3c}$

Step-by-step explanation:

You want x alone on the left side.

x is being multiplied by 3 and by c.

The opposite operation of multiplication is division. You must divide 3xc by 3c to end up with just x.

You must do the same operation to both sides of an equation, so divide both sides by 3c.

$3xc = -5$

Divide both sides by 3c.

$\dfrac{3xc}{3c} = \dfrac{-5}{3c}$

Simplify both sides.

$x = -\dfrac{5}{3c}$
