Nathan ordered one cheeseburger and one bag of chips for 3.75 jack ordered two cheeseburgers and three bags of chips for 8.25 kn
Elan Coil [88]

Answer:

cheeseburger is $3 and chips is $0.75

Step-by-step explanation:

Let price of cheeseburger be x while price of a bag of chips be y hence for the case of Nathan, we can write the equation as x+y=3.75. Similarly, for Jack, we can write it as 2x+3y=8.25

x+y=3.75 hence x=3.75-y and substituting this into the second equation we have

2x+3y=8.25

2(3.75-y)+3y=8.25

7.5-2y+3y=8.25

y=8.25-7.5=0.75

x=3.75-y=3.75-0.75=3

Therefore, price of cheeseburger is $3 and chips is $0.75

Y = 4x - 3<br> (Solving for slope)
olasank [31]

Answer:

Slope = 4

Step-by-step explanation:

This is an equation of a line in the format y = mx + b

Lets match the two equations vertically to see which term is which

y = mx + b

y = 4x - 3

m is the slope, and it matches with the term "4"

That means that 4 is the slope

Parts of y = mx + b

  • y : output
  • m : slope
  • x : input
  • b : y - intercept
