Question

Use the graph to derive the equation y = mx for a line through the origin. simplify the numerical coefficient, if needed.
graph coordinates are, (3,3),(8,8)
answers
y=8x
y=x
y=3/3x
y=3x

Answer 1

The proportional relationship between inches and feet is displayed on the graph. Derive the equation of the line through the origin.
inches per feet. 1 foot, 4 inches.
graph coordinates: (1,12),(2,24),(3,36)
answers
y=2x
y=12x
y=36x
y=1/12x

Answer 2

complete the ordered pairs in the table by finding the y-value of the ordered pairs for the equation y=5x.

x,y,(x,y)
0,_,(0,_)
1,_,(1,_)
2,_,(2,_)
answers:
a.(0,0),(1,5),(3,15)
b.(0,0),(1,1/5),(2,2/5)
c.(0,0),(5,1),(10,2)
d.(0,0),(1,5),(2,10)

Answer 3

Graph the proportional relationship y=-2x by plotting points.
a. (0,0),(1,-2),(2,-4)
b. (0,0),(1,5),(2,10)
c. (0,0),(1,2),(2,4)
d. (0,0),(1,-1),(2,-2)

Answer 4

Is this the correct graph of the equation y=1/5x?
graph: (0,0),(5,1)

answers:
a. yes, it is the correct graph because the ordered pair (0,0) satisfies the equation and the slope m = rise/run = 1/5.
b. No, it is not the correct graph because the slope m = rise/run = 1/5.
c. Yes, it is the correct graph because the slope = 5/1.
d. No, it is not the correct graph because the ordered pair (1, 5) is not a point on the graph of y = 1/5 x.

Answer 5

All answers except "no, it's not the correct graph" are correct. the correct answer for 5 is "yes, it is the correct graph because the ordered pair (0,0) satisfies the equation. . ."
