If you were to write the equation of this line in the form y=mx+c what is the value of m

marusya05 [52]

Answer:

B choice.

Step-by-step explanation:

The graph decreases. Therefore, the slope is in negative. We can rule out A and C choices.

It is very obvious to tell because of steepness. Low steepness = low value

High steepness = high value.

We can also find the slope by using rise/run.

$m = \frac{dy}{dx}$

The change of y over the change of x.

Given the coordinate points (0,1) and (4,0). Both points are part of the graph.

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{1 - 0}{0 - 4} \\ m = \frac{1}{ - 4} \\ m = - \frac{1}{4}$

Therefore the value of m is - 1/4

Solve 0.252x = 41. Round your answer to the nearest hundredth

Oksana_A [137]

0.252x = 41

In Algebra, we must keep the equation balanced. What we do to one side, we must do to the other. We also need to isolate the variable x.

Since x is multiplied by 0.252, we must divide the left side by 0.252 to get rid of the 0.252. But, to keep the sides equal, we must do it to both sides.

0.252x/0.252 = 41/0.252

This leaves us with x = 162.69

Step-by-step explanation:

since they gave the point (0,0) and slope 3

y=mx+b
