Question

What goes on the lines I don’t understand the problem

Answer 1

Explanation:

a). Let the number of spoons = x

And number of forks = y

Total number of spoons and forks bought by Perry = 10

x + y = 10 --------(1)

Cost of one spoon = $5

Cost of one fork = $3

Therefore, total cost of x spoons and y forks = $(5x + 3y)

5x + 3y = 42 -------(2)

b). Now we can convert these equations into the slope-intercept form.

x + y = 10 ⇒ y = -x + 10

Table for input output values,

x 2 4 6

y 8 6 4

5x + 3y = 42

3y = -5x + 42

y =
`-(5)/(3)x+14`

x 0 3 6

y 14 9 4

Point of intersection of these lines will be (6, 4).
