First we can find the ratio by dividing one of the points on the graph.

12 / 3 = ? @TheUnknownShadow

I will look for a link to help in the future

anonymous · Answer

Make an equation from your graph using the slope and a point to determine the y-intercept (though you can extrapolate from the slope on the graph) and then plug in the number for y and solve for x.

Can you divide 12 / 3? @TheUnknownShadow

anonymous · Answer

It has a slope of 4 yes.

anonymous · Answer

Since 1 pizza feeds 4 people, multiply 4 x 10 to get 40, and multiply 10 to 1 to get the amount of pizzas you need to feed 40 people.

anonymous · Answer

It will have a y-intercept of (0, 0)

Since the y-intercept is (0, 0)

anonymous · Answer

Now set y = 40
