Hey!
-------------------------------------------------
This function is written in point-slope form.
Where y1 and x1 show one coordinate and m is the slope.
We have the coordinate (5, -1) and the slope of 2.
By graphing the function we can now see the y-intercept of -10.
Slope-Intercept Form: y = 2x - 10
Function graphed below!
