Answer:
Step-by-step explanation:
Hi there!
Slope-intercept form: where is the slope and is the y-intercept (the value of y when x is 0)
<u>1) Determine the slope (</u><u><em>m</em></u><u>)</u>
where two given points are and
Plug in the given points (15,2.2) and (5,1.6):
Therefore, the slope of the line is . Plug this into :
<u>2) Determine the y-intercept (</u><u><em>b</em></u><u>)</u>
Plug in a given point and solve for b:
Therefore, the y-intercept is . Plug this back into :
I hope this helps!
