Answer:
Step-by-step explanation:
y=mx+c
where m is the gradient and c is the y-intercept of the line
Let's find the gradient of the line first.
Using the above formula,
Subst. the gradient into m:
Now, find the value of c by substituting a coordinate into the above equation.
when x=-1, y=3,
Therefore the equation of the line is
The right answer is Option C.
Step-by-step explanation:
Given,
Pizzas made by Paul on first day = 12
Pizzas made each day after that = 6
Let,
p represent the number of pizzas made after first day.
Total pizzas = 6p + 12
Number of days = 8 because first day 12 pizzas are made
Total pizzas =
Pizzas made by Cindy on first day = 16
Pizzas made each day after that = 4
Total pizzas = 4p + 16
Total pizzas =
Paul has made more pizzas after 9 days. He has made 60 pizzas.
