2x*x=2x^2
2x*-y=-2xy
3y*x=3yx
3y*-y=3
2*x=2x
2*-y=-2y
-3x*x=-3
-3x*-y=3xy
combine like terms and that is your answer

Answer: y = 0.5x + 35
Step-by-step explanation:
let x represent the number of minutes used by the customer in a month.
Let y represent the monthly cost for x minutes.
If we plot y on the vertical axis and x on the horizontal axis, a straight line would be formed. The slope of the straight line would be
Slope, m = (435 - 215)/(800 - 360)
m = 220/440 = 0.5
The equation of the straight line can be represented in the slope-intercept form, y = mx + c
Where
c = intercept
m = slope
To determine the intercept, we would substitute x = 360, y = 215 and m = 0.5 into y = mx + c. It becomes
215 = 0.5 × 360 + c
215 = 180 + c
c = 215 - 180
c = 35
The equation becomes
y = 0.5x + 35
