Answer 1

y=9x-11

Explanation:

To write the equation of a line we must have a slope and a point. To find the slope we use the slope formula and substitute (x,y) points in it as shown below:

`m=(y_2-y_1)/(x_2-x_1)=(61--38)/(8--3)=(61+38)/(8+3)=(99)/(11)=(9)/(1)=9`

Now that we have the slope, plug in the slope and choose one point to plug into the point slope formula. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form.

(y--38)=9(x--3)

(y+38)=9(x+3)

y+38=9x+27

y=9x-11
