Answer:

Refer to the graph with Slope(m) = 4 and Y-Intercept

=

8

Step-by-step explanation:

y

=

m

x

+

b

is the equation of a straight line usually written this way, where

m

represents the Slope ( or Gradient ) and

b

the Y-Intercept. It is also in Slope-Intercept Form.

Also,

m

=

r

i

s

e

r

u

n

or ( Change in y)

/

(Change in x)

We need to graph

y

=

4

x

8

We observe that it is already in Slope-Intercept Form.

Hence, Slope =

m

=

4

Y-Intercept

=

(

8

)

Go to the graph and plot the point the point

(

0

,

8

)

on the y-axis.

Then rise 4 and run 1. Plot the point

(

1

,

4

)

Then again "rise 4" and then "run" 1. Plot the point

(

2

,

0

)

Join all these points on the graph and you will find a straight line. graph{4x - 8 [-19.75, 20.25, -14.88, 5.12]}

Also refer to an additional graph available with my suggested solution with points plotted.

Hope this helps.
