Question

I desperately need help.

Madison and Lucas went to the fair. Madison rode 8 rides and spent $20. Lucas rode 5 rides and spent $17. Write a linear equation, in slope-intercept form, that models the cost y of one person going on x rides. You can write the equation in any form.
1. Write an ordered pair representing Madison's data. Remember: ordered pairs look like (2,6)
2. Write an ordered pair representing Lucas's data. Remember: ordered pairs look like (2,6)
3. Calculate the slope
4. Write the Equation of the line

Answer 1

first solve for x

8x=20

x=2.5

5x=17

x=3.4

then your equations

Madison: y=2.5x

Lucas: y=3.4x

then your ordered pairs

Madison: (4,10)

Lucas:(3,10.2)

then your slope

Madison-2.5

Lucas-3.4

I hope this is good enough:
