Slope-intercept equation:
y=mx+b
Where;
m= slope
b= y-intercept
First, we have to find the slope (m). Apply the formula:
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
Select 2 coordinate points from the table:
(x1,y1) = (5,60)
(x2,y2) = (6,73)
Replacing;
[tex]m=\frac{73-60}{6-5}=\frac{13}{1}=13[/tex]
So far we have:
y= 13x+b
Plug a coordinate point (x,y )from the table in the equation and solve for b.
For example (x,y) = (5,60)
60 = 13 (5) + b
60 = 65 + b
60-65 = b
b= -5
Final equation:
y= 13x-5
