Answer:

y=mx+b

m=sloe

b=yint

given

slope=-2

yintercept=8

Step-by-step explanation:

y=-2x+8

add 2x to both sides

2x+y=8

minus 8 both sides

2x+y-8=0

It is 3 but it is different a little bit because you need to move the y to the other side

What would 2x + 3y = 1,470 be in slope intercept form and how do you get it
Flauer [41]

slope intercept formula is y = mx + b.

Isolate the y. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS. First, subtract 2x from both sides

2x (-2x) + 3y = (-2x) + 1470

3y = -2x + 1470

Isolate the y. Divide 3 from both sides

(3y)/3 = (-2x + 1470)/3

y = (-2x + 1470)/3

Simplify

y = (-2/3)x + 490

y = (-2/3)x + 490 is your answer

hope this helps

Need to pass this test to graduate
Paraphin [41]
The 1st graph has vertex in (-3, -3) which can be translated into
Horizontal shift left 3
Vertical shift down 3
Other than that, the graph shows y=x^2 so it wasn't compressed or stretched

The 2nd graph has vertex in (0, 0) which mean there is no vertical and horizontal shift. But the graph is facing down and it was slimmer than y=x^2 graph. When x=1, the result is y=3 which was 3 times more than it supposed to be.
The graph must be:
Reflection across x-axis
Vertical stretch of 3

The 3rd graph has vertex in (3, -3) which can be translated into
Horizontal shift right 3
Vertical shift down 3
Same as the 1st graph, the 3rd graph shows y=x^2 so it wasn't compressed or stretched.
