Can someone please show me how to answer this question? Please? Graph the following equations using the point-slope method or intercepts method. (1 pt) Show the steps of the procedure as outlined in the lesson as you graph the lines. (1 pt) Draw your y-intercept in yellow, your other points in red and your line in blue. 9x + 12y= -36

Your choice: point-slope method or intercepts method?

@mathmale which do you think will be easier ?

For 9x + 12y= -36 I'd use the intercept method. Let x = 0 and find y. Then the y-intercept is the point (0, ? ) Let y = 0 and find x. Then the x-intercept is the point ( ? , 0) Plot these on coordinate axes and draw a line thru both points.

y-intercept: Let x = 0 and find y. Letting x=0, 9(0) + 12y = -36. What is y?

24? @mathmale

9(0) + 12y = -36 0 + 12y =- 36 Try again @abbycross167

-24? @Directrix

I think you are adding 12 to -36. That is not what the equation is asking you to do. 12y =- 36 Divide both sides by 12. What is -36 divided by 12?

Yes. Let me read through the thread to see what we are supposed to do next.

For 9x + 12y= -36 I'd use the intercept method. Let x = 0 and find y. Then the y-intercept is the point (0, -3 ) Let y = 0 and find x. Then the x-intercept is the point ( -4 , 0) Plot these on coordinate axes and draw a line thru both points.

Click on the pencil and sketch the line in blue. Recall that two points determine a line. |dw:1449885003902:dw|

like that? I couldn't find a blue line

Extend it. A line does not have a beginning and ending point. Look at this. You can always go over to desmos.com and draw all sorts of graphs.

The problem you posted asks for those colors. That is why I mentioned them.

Yes sir/ma'am I know how to do the colors on my school thing, I just couldn't figure out how to do it on here

Alrighty, then. You are welcome. Thanks for being interactive in the thread. Math is more fun that way.
