Me due todayyy i beg of pl no one would me someone

Part A:

the value of the y-intercept or b (50) represents the amount of customers that were at the restaurant at 7pm because according to the problem, it says that x = 0 at 7pm. the y-intercept is (0, y)

Part B:

so you had the right idea, except instead of everything going by ones, its going by fives

every square represents 5 so the line is going down every two squares, then 5(2) = 10 and because the line is going down it would be negative

therefore, m = -10

Part C:

all you have to do now is put part a and b together

y = mx + b

m = -10 and b = 50

y = -10x + 50

or (depending on what you're doing in your class)

f(x) = -10x + 50

Part D:

at 8:30pm, you should expect 35 customers at the restaurant. this is because the (0, 50) represents the amount of customers at 7pm, so an hour an a half later would be (1.5,y) if you use the equation and plug in the 1.5 for x then it should look like this:

y = -10(1.5) + 50

y = -15 + 50

y = 35

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.

step-by-step explanation:

hope this !
