Step-by-step explanation:
Hi there!
Slope intercept form: where m is the slope of the line and b is the y-intercept (the value of y when the line crosses the y-axis)
<u>1) Find the slope (m)</u>
where the two given points are
and
Plug in the given points (2,8),and (8,2)
Therefore, the slope of the line is -1. Plug this into :
<u>2) Find the y-intercept (b)</u>
Plug in a given point and solve for b
Add 2 to both sides
Therefore, the y-intercept is 10. Plug this back into :
I hope this helps!
