Question

6)The number of sofas a factory produces varies directly with the number of hours the machinery is operational. Suppose the factory can produce 455 sofas in 48 hours. What is an equation that relates the number of sofas produced, n, with the amount of time, t, in hours? What is the graph of your equation?A. n = 9.48t
B. n = 0.11t

C. t = 4.74n
D. t = 9.48n

8)Write an equation of a line with the given slope and y-intercept. m = –5, b = –3
A. y = –5x – 3

B. y = –5x + 3

C. y = 5x – 3

D. y = –3x – 5

10)What is the graph of the equation? y = –2

Answer 1

9)Write the slope-intercept form of the equation for the line.

Answer 2

@I4NI heres my last four questions

Answer 3

6)\[A. n=9.48t\]
Because;
\[\frac{ 455sofas }{ 48hours }\]
\[455\div48\approx9.48\]
When n = amount of sofas produced in t amount of hours.

Answer 4

dsfdsf
\[y=mx+b\]
\[m=-5\]\[b=-3\]
Plug in values;
\[y=-5x-3\]
So the answer is A.

Answer 5

10) The graph of y = -2 is just a straight line since -2 is just a y-intercept and never changing.

Answer 6

For you last question #9 I can't tell what the y and x intercepts are again :p

Answer 7

@I4NI 9) the points at the end on the lines are the numbers i put

Answer 8

Does the line cross the y-axis at 3 and the x-axis at -4? Or does it not say what the line is?
