Question

Not sure how to do this

Answer 1

Explanation:

`slope=(rise)/(run)=(\Delta y)/(\Delta x)\\\\\Delta y-\text{run up (+) or down (-)}\\\\\Delta x-\text{run to the right (+) or to the left (-) }\\\\\text{We have}\ slope=-(1)/(2)=(1)/(-2)\to\Delta y=1\ (\text{1 unit up}),\ \Delta x=-2\ (\text{2 units to the left})\\\\\text{Mark the point (-3, 5) in the coordinates system. Go 1 unit up}\\\text{and 2 units to the left. Mark next point.}\\\text{Draw a line passing through the given points.}\\\\\bold{Look\ at\ the\ picture.}`

Answer 2

Answer in picture.

Explanation:

First step: You must plot the point (-3,5).

To graph this point, start at the origin.

The point says move left 3 and up 5 and put your dot (your point).

Second step: Use your slope to find a second point to plot. The slope is
`(-1)/(2)`.

Slope is rise/run. So it says down 1 and right 2.

So starting at the first point you plotted and you count down 1 and then go right 2 and put your second point.

Third step: Connect the two points with a straight-edge. Extend in both directions.

The two points I used to graph my line is (-3,5) and (-1,4).
