What is the equation of this graphed line? (2,,-6)

For this case we have that by definition, the equation of the line of the slope-intersection form is given by:

Where:

m: It's the slope

b: It is the cut-off point with the y axis

To find the slope we need two points through which the line passes, according to the image we have the following points:

The slope is given by:

Thus, the equation is of the form:

We found "b" replacing one of the points:

Finally, the equation is of the form:

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
