Question

Please help me answer question 1,2 and plot this graph

Answer 1

b: When x increases by 1, y increases 1 unit.

c. Apply the slope formula (m)

`m=((y2-y1))/((x2-x1))`

Replace with 2 points form the table:

For example:

Point 1 = (x1,y1)= (0,3)

Point 2= (x2,y2)= (1,4)

Replacing:

`m=(4-3)/(1-0)=(1)/(1)=1`

Slope = 1

It doesn't need to be written because x multiplied by 1 is equal to x.

Graph.

y=mx+b

y=x+3

Where :

b= y-intercept = 3( where the line crosses the y-axis)

m= slope=1
