Q15. Please explain the work that comes with it in length and explaination also please and thank you

Answer 1

Let's construct the equation in slope-intercept form. Start by finding the slope of the line.

`(y-y)/(x-x)=(9-12)/(2-3)=(-3)/(-1)=3`

This gives us y = 3x + b. Now, find b (or the y-intercept) by inputting a coordinate pair given in the table.

`y=3x+b`

`9=3(2)+b`

`9=6+b`

`3=b`

This gives us the completed equation of y = 3x + 3.

The correct answer is B) y = 3x + 3.
