Question 120958:
Find an equation in slope-intercept form passing through the points (7.2,3.8) and (9.1,9.1).
Answer by checkley71(8403) (Show Source): You can put this solution on YOUR website!
slope=(9.1-3.8)/(9.1-7.2)=5.3/1.9
Y=mX+b
3.8=5.3/1.9*7.2+b
3.8=5.3*7.2/1.9+b
3.8=20.08+b
b=3.8-20.08
b=-16.28
Y=5.3X/1.9-16.28 ANSWER.
(graph 300x300 pixels, x from -10 to 10, y from -10 to 10, y = 5.3x/1.9 -16.28).
