1. Write a formula that describes the function for: A large pizza costs $12.00 plus 30 cents for each topping. Express the total cost C as a function of the number of toppings t.
C = .3t + 12 is the function
or, you can graph this as y = (3/10)x + 12
-------------------------------------------------------------------------------
2. Graph 5y - 3x >= 25
5y >= 3x + 25
y >= (3/5)x + 5
graph y = (3/5)x + 5 as a solid line .... then, shade above the solid line
Solved by pluggable solver: DESCRIBE a linear EQUATION: slope, intercepts, etc
Equation describes a sloping line. For any
equation ax+by+c = 0, slope is .
  • X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 25/-3 = -8.33333333333333.
  • Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 25/5 = 5.
  • Slope is --3/5 = 0.6.
  • Equation in slope-intercept form: y=0.6*x+5.
