y = 1.5x + 1.5

Step-by-step explanation:

Since it says it is growing at a constant rate, it means that is linear.

The linear formula follows this form: y = mx + c, where m is the gradient and c is the y-intercept

To find the gradient, you sub the values into the gradient formula.

That would be 4.5 - 3.0 divided by 2-1

That would be 1.5/1 = 1

Hence the gradient is 1.5

y = 1.5x + c

To find c, you sub in one point into the equation

I'm going to go with (3, 6.0)

6 = 1.5*(3) + c

6 - 4.5 = c

c = 1.5

Hence the formula is: y = 1.5x + 1.5

pay attention in your classes and concentrate the best thing you can do to raise your test scores is to pay attention when you're supposed to be learning the material: in class!

take good notes.

do your homework.

use mnemonics and other tricks.

do practice tests.

note: the best i know.
