Brainliest Answer.

Step-by-step explanation:

Hey there!

Given;

The points are ; (8,9) and (-2,4).

A. To find: Slope.

Use slope formula.

Put all values.

Therefore, slope (m) = 1/2.

B. The equation of a line in point slope form is;

Using point slope form of equation we get;

Put all values.

Therefore, the equation of a straight line in point slope form is; (y-9) = 1/2(x-8).

C. Let's convert the above point slope form in slope intercept form.

Therefore, the equation is y = 1/2x + 5.
