A linear function is given by the equation y=4x. Using the points x and x+1, show that the y-values increase by 4 between any two points separated by x2−x1=1

gives

Step-by-step explanation:

Given

Required

Show that the y values increases by 4 for

We have:

For

Substitute

For

Substitute

So, we have:

Subtract from

Collect like terms

Hence:

gives

i.e. an increment of 4

the answer

b. they are parallel and will never intersect.

what is the original number? you forgot to add it.
