Question

Can someone please help me answer this question?
Graph the following equations using the
point-slope method. Graph the point from the equation in yellow, your other points in red and your line in blue. y - 7 = -3(x + 2)

Answer 1

@flcon04 Could you show me how to do this?

Answer 2

Any ideas?
:-)

Answer 3

well I did it once but my teacher said I got it wrong, would you like me to show you what I did?

Answer 4

Ok

Answer 5

Sorry it took so long! but the dot on 1 is yellow and the dot on -3 is red

Answer 6

Answer 7

the "point-slope method"

First you need to change the given equation y-7=-3(x+2) into the point-slope form

Recall the distributive property a(b+c)=ab+ac and use it on the right hand side of the equation.

y-7=-3x-6

$$\huge y=-3x+1$$

Try to graph that^
:-)

Answer 8

isn't that what I did?

Answer 9

Nope

Answer 10

oh

Answer 11

You have the right y-intercept, but the slope is not right.

Answer 12

what would the slope be?

Answer 13

-3

Answer 14

I'm confused, could you show me how to graph it? I really thought I did it right

Answer 15

y = mx + b

y = -3x + 1

Answer 16

I put a dot on -3

Answer 17

Do you see why the slope m = -3?

Answer 18

The dot you put on -3 is a point on the x-axis.

That is not what is meant by the word "slope."

Answer 19

so -3 needs to be on te y-axis?

Answer 20

Nope.

Answer 21

Slope tells you how to go from one point on the line to another.

Answer 22

hmm I don't understand this

Answer 23

Have you tried the khan academy on YouTube?

Answer 24

yes sir but I couldn't find a video that helped me with this problem... Could you please show me what the graph should look like?

Answer 25

Sir/ma'am*

Answer 26

Start at the point (0,1) and go down 3 and to the right 1.

That^ will give you a second point.

Answer 27

(1, -2)

Answer 28

like that?

Answer 29

Nope

Answer 30

(0, 1),

(1, -2)

Answer 31

oh I'm sorry, math isn't my best subject

Answer 32

Plot those^ two points and draw a line through them :-)
