 y - 7 = -3(x + 2)

ram231 · Answer

well first you have to distribute the -3(x+2) to get rid of the parenthesis. so it would be -3x+-6. so the equation now is y-7=-3x+-6 can you figure out the rest of the equation?

umm no ma'am... I'm not very good at math

ram231 · Answer

hmm. so. i can't give you the straight up answer. wish I could. but I will lead you through it okay?

 y - 7 = -3(x + 2)

Please note that this equation is already in "point-slope" form.  See that "x+2?"  This means that the x-coordinate of one of the points on this line is -2.  See that "y-7?"  This means that the y-coordinate of that point on the line is 7.

Graph the point (-2,7), please.

You can read the slope (m) directly from the given equation.  What is it?

So since -3x+-6 is basically like -3x-6 right? well y-7=-3x-6 you need to get the variables on one side of the = sign, while the others are on the other side. so can you do that?

abbycross167 · Answer

y-7-3x=-6?

abbycross167 · Answer

@mathmale does m = -3?

ram231 · Answer

so in y-7=-3x-6, its like adding 7 to the 6. so its off of that side. so now the equation is y=-3x+1 now how do you get the -3x on the other side of the = sign?

abbycross167 · Answer

1-3=2?

abbycross167 · Answer

or would it be -3-1=-2?

ram231 · Answer

Well I basically gave you the equation to use. y=-3x+1... so 1 would be the y intercept, and -3 would be m... in the equation mx+b=c2 so... how I am writing the equation in my explanation is c2=mx+b. the b variable would be the y intercept right?

abbycross167 · Answer

yes ma'am so that would be 1?

ram231 · Answer

yes. and m would be -3

abbycross167 · Answer

ok so on a graph x=-3 and y=1?

ram231 · Answer

yes.

abbycross167 · Answer

ok you're awsome thank you soo very much!! Could you please help me with one more I have to turn it in by 12:00am

ram231 · Answer

sure thing. you can either make a new question or just continue on this.
