Question

Let the number of games, x, and the number of rides y, For 2x + 4y = 20, what is the slope of the graph? What is the slope? (Hint: Solve for y) Write the y-intercept as an ordered pair? (Hint: x=0 at the y-intercept) 10 Write the x-intercept as an ordered pair? (Hint: y = 0 at the x-intercept)​

Answer 1

m= -1/2, (0,5), (10,0)

Explanation:

Let us write it in slope intercept form, y=mx +b where m is the slope:

2x+4y=20

4y= -2x+20

y= -1/2x+5

Therefore, the slope is -1/2

The y intercept can be found when we substitue 0 as x.

y= -1/2*0 +5

y=0+5

y=5

(0,5)

The x intercept can be found when we substitute 0 as y.

0=-1/2x+5

-5 =-1/2x

x= 10

(10, 0)

I hope this helped! :)
