Evaluate the following expression for y = - 2. - 3 y

bekas [8.4K]

Answer:

-1/8

Step-by-step explanation:

The given expression is y⁻³

We want to find the value of the expression when y = -2

Thus;

At y = -2, we have; -2⁻³

According to law of exponents, x⁻⁴ = 1/x⁴

Thus; -2⁻³ = -1/2³ = -1/8

Characterize the slope of the line in the graph

katen-ka-za [31]

Answer:

Please check the attached graph.

Step-by-step explanation:

Note: You did not add the graph; so I am taking a sample graph to clear the concept anyway. Please check the referred graph attached below.

The slope on the graph basically tells us the time rate of change.

In other words, it describes the steepness of a straight line.

The slope can also be termed as:

Slope = rise / run

From the attached graph, taking twp points

(0, 3)

(-1, 0)

Finding the slope between (0, 3) and (-1, 0) using the formula

$\left(x_1,\:y_1\right)=\left(0,\:3\right),\:\left(x_2,\:y_2\right)=\left(-1,\:0\right)$

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{0-3}{-1-0}$

$m=3$

Thus, the slope of the given line on the graph = m = 3

5x-2 what’s the slope and y-int ?

uranmaximum [27]

Answer:

Slope = 5.

y-int = (0, -2).

Step-by-step explanation:

y = 5x - 2

The slope intercept form is

y = mx + b where m = the slope and b = the y-intercept.

So here, the slope = 5 and the y-intercept is where y = -2. That is the point (0, -2).
