Step-by-step explanation:
Which linear function is represented by the graph?
1 answer:
Answer:
yx-4; B
Step-by-step explanation:
The blue is in the y-values where it is more directed towards the negative y- values.
y=mx+b
slope= because rise is 1 and 3 runs and to find slope it is
-4 is the "b" in y=mx+b where b represents the y-intercept and looking at the graph, the line intercepts at -4

Answer:
Trail Mix costs $2.50 per pound, and Jelly Beans cost $1.50 per pound.
Step-by-step explanation:
Using x for trail mix and y for jelly beans, we have a system of equations being
We can solve this system using substitution
5x+3y=17
Divide by 5 to have a coefficient of 1 before x
Subtract from each side to single out one variable to one side
Now, we can plug in our value for x into the given equation
Open the parentheses
Merge Y values
Separate numerical values from variables
Divide by 10.8 in order to have a coefficient of 1
Now that we have one of the values, we know that a pound of jelly beans costs $1.50. We can now plug in 1.5 for y into one of our equations to find x.
Open parentheses
Single out the variable
Divide by 5 to have a coefficient of 1 before x
