1+(1−1)×(−4.1)
=1
1+(4−1)×(−4.1)
=−11.3
1+(10−1)×(−4.1)
=−35.9
The answer is A. When you take the 9s and the -2s, you get 7s. Then you add the 3x5 and end up with 15. Giving you the answer 7s+15
The answer would be 3mph because 3/4 / 1/4 = 3. So the answer would be 3mph.
For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

Where:
m: It's the slope
b: It is the cut-off point with the y axis
On the other hand we have that if two lines are perpendicular, then the product of their slopes is -1. So:

The given line is:

So we have:

We find 

So, a line perpendicular to the one given is of the form:

We substitute the given point to find "b":

Finally we have:

In point-slope form we have:
