Solve for y, then plot (since x is the independent variable & y is the dependent variable)
x + 2y = 10
*subtract x from both sides, and divide both sides by 2 . . to get . .
y = -1/2x + 5In slope intercept form:
y = mx + b
m = slope = -1/2 . . . the rise/run of the line . . . rise = -1 units, run = 2 units
b = y-intercept = 5 . . . where the line crosses the y-axis
(see the attached plot)

the correct answer is A
Answer:
A)
B) $1200
Step-by-step explanation:
Let w represent employee's weekly sales and be total weekly earnings.
We have been given that a phone store employee earns a salary of $450 per week plus 10% commission on her weekly sales.
A) The total weekly earnings of employee would be weekly salary plus 10% of weekly sales.
10% of weekly sales, w, would be
Therefore, the function models the employee's weekly earnings.
B) To find the weekly sales in the week, when employee earned $570, we will substitute in our formula and solve for w as:
Therefore, the amount of employee's weekly sales was $1200.
