Answer 1

Where is the line?

Answer 2

Do you know the slope formula?

Answer 3

It's important that you know the formula for the slope of a straight line passing through two given points. It is\[m=slope=\frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }\]

Answer 4

where the two points are \(\bf (x_1,y_1)\) and \(\bf (x_2,y_2)\)

Answer 5

Note that two points resting on the same straight line are given: (-5,4) and (2,-3).

You may choose either point to be point #1 and then call the other point #2.

Answer 6

Please show all the work you do to calculate the slope, m, using the above formula.

Answer 7

(-5,2) and (4,-3)

Answer 8

Yes. So, identify:\[x _{1},y _{1},x _{2},y _{2}\]

Answer 9

wrong

Answer 10

and plug these values into the slope formula, given above.

Answer 11

The points are (-5,4) and (2,-3)

Answer 12

Actually, John, you could pick any points you want that rest upon the given line. But with two points on that line already identified, it'd save time to use the given points.

Which do you want to do?
