Question

All i need is number 6 and 7. Thank you if you can do

Answer 1

Answer:

6) I attached the graph as an image, or you could just use Desmos for better detail

7) y = x - 3

Step-by-step explanation:

7) Take two points and do the change in y / change in x

So if you take points (6,3) and (3,0), the change in y is 3 and change in x is 3, giving 1 as the gradient.

Next, find the y intercept which is where the line meets the y axis, so -3.

Answer would come out as y = x - 3

Answer 2

Answer:

Step-by-step explanation:

y=-1/5x+2

make a list of at least 2 points:

if x=0 y=-1.5*0+2=2

if x=2 y=-1.5*2+2=-1

(0,2) and (2,-1)

7.

take three points:

(3,0), (0,-3), (4,1)

Try to find a pattern.

3-3=0

0-3=-3

4-3=0

x-3=y

So the answer is x-3=y or y=x-3.
