Functions, Slopes, Y-intercepts & Function Tables -
0,50=y-intercept
Why? Well y is by itself meaning it's the intercept of the graph which is intersecting within the y axis.
I find slope by using the formula:
[tex] \frac{y1 - y2}{x1 - x2} [/tex]
I will be using the first two functions:
(0,50) & (1,75)
Plug them in!
[tex] \frac{50 - 75}{0 - 1} [/tex]
Evaluate them up!
[tex]\frac{ - 25}{ - 1} [/tex]
slope=25!
