Question

Match the term with the appropriate definition grphs will be added
1.9x + 3y =6
2.3x - 2y =12
3.x - 2y =6
4.y=4^3 x - 3
5.y= -3 ^4 x +3
6.-2x + y = -3
7.x +3y =9
8. y +4 = - 1^3 (x - 6)

Answer 1

Try converting them into slope-intercept form. Then it'll be easier to find the graph of each.

Answer 2

i dont know how to do that

Answer 3

Ok do you know the slope-intercept form?

Answer 4

no i do not im new to all this

Answer 5

thats y im looking for help

Answer 6

Ok:
Standard form: ax + by = c
Slope-intercept form: y = mx + b
Point-slope form: y - y1 = m(x - x1)

Answer 7

The first one is in standard form and we want it it slope-intercept:
9x + 3y =6
SO we want the y alone,
9x + 3y =6
-9x
3y = -9x + 6
/3 /3 /3
y = -3x + 2

Do you understand so far what I'm doing?

Answer 8

Ok, After u change them to slope-intercept form just plot them on the graph:
just remember that:
y = mx + b
m = slope
b = y-intercept(where the line crosses y axis)
so for example y = -3x + 2 the slope is -3/1 and the y-intercept is 2. So plot the y-intercept 2 at point (0,2) and then use the slope(-3/1) to find the next point.
rise/run so from (0,2) go down 3 spaces and to the right 1 space.

Answer 9

So the first equation the answer is graph E.
For the equations that are in point-slope form...just distribute and solve for y..then follow the same steps to graph as above.
