English translation:

determine the equation and the graph of the straight line that has as slope m = - 1 and ordinate b = 6

Hi. So one thing we can do here is to use Desmos to graph it out. But that's not what you want to do first.

The equation for the slope of a line is y=mx+b where x is the coordinate on the x axis, y is the coordinate on the y axis, m is the slope, and b is the y intercept.

Good so far? (Reply to this answer if you need help here or on any other part in particular.)

So now we can plug in the m value. This gives us y=-1(x)+b. Also reprsented as y=-x+b by the way.

Now that we plugged in m, plug in b: y=-x+6.

This gives us the equation of the line. Use this to plot the graph as seen below.

I hope you understand how I got to the equation. If not, comment below.

Enjoying week 24 of Int to Geo?

These have been solved here:

And also, don't try to get people to do the proof for you. You will be in a lot of trouble with the proof part if you are caught.
