Graph the line with slope -3 passing through the point (3,-4)

Vinvika [58]

Given: $\textsf{Slope = -3, Passes through (3, -4)}$

Find: $\textsf{Equation in slope-intercept form}$

Solution: The first step that we need to take is to plug the given values into the point-slope formula which would help us out since we have both the slope and a point. Using that we would then distribute on the right side of the expression and then subtract 4 from both sides which would isolate y.

Plug in the values

$y - y_1 = m(x - x_1)$

$y - (-4) = -3(x - 3)$

Distribute

$y + 4 = (-3 * x) + (-3 * - 3)$

$y + 4 = -3x + 9$

Subtract 4 from both sides

$y + 4 - 4 = -3x + 9 - 4$

$y = -3x + 9 - 4$

$y = -3x + 5$

Therefore, after plugging in the values and completing the rest of the steps we were able to determine that equation of the data provided would be $y = -3x + 5$ .

What is the equation for density? D = d = m over v. D = d = v over m. D = d = m over v squared. D = d = one-half m v squared.mv2

Sophie [7]

Answer:

d = m / v.

Step-by-step explanation:

The density is a measure of the specific weight of a substance or object.

This is, the mass per unit of volume. Then, the average density is the ratio of the mass of a body to the volume it occupies in space:

The equation for density is:

$\bar d=\dfrac{m}{V}$
