Brand a: per fork is 0.06 cents.
Brand b: per fork is 0.05
Choose brand B!
Slope-intercept form: y = mx + b [m is the slope, b is the y-intercept or the y value when x = 0 ---> (0, y) or the point where the line crosses through the y-axis]
To find the slope, use the slope formula (m):
and plug in the two points
(6, 8) = (x₁, y₁)
(9, 6) = (x₂, y₂)


Now that you found the slope, plug it into the equation
y = mx + b
To find b, plug in one of the points, I will use (6, 8)

8 = -4 + b Add 4 on both sides
12 = b Now plug in b into the equation

To reduce the fraction in its simplest form...first find the greatest common factor of the numerator and the denominator..so in this case is 8.
Now lets divide the numerator by the GMF;
16 ÷ 8 =
2 Next the denominator;
24 ÷ 8 =
3
So

Hope this helps! :D
