What is the equation of the graph?
A. y=4x
B. y= 1/4x
C. y=-1/4x
D. y= -4x

Answer:
y =4x
Step-by-step explanation:
First find the slope
We have point (0,0) and point (4,1)
The slope formula is
m = (y2-y1)/(x2-x1)
= (4-0)/(1-0)
= 4/1
The slope is 4
The y intercept is 0
The slope intercept form of the line is
y = mx+b where m is the slope and b is the y intercept
y = 4x+0
y =4x
Answer:
Answer B is the correct one: y = (1/4)x
Step-by-step explanation:
This straight line passes through the origin, so the y-intercept (b) is zero (0).
Next, we see that the slope of the line is positive, so that eliminates answers C and D.
Finally, we see that the slope of the line is m = rise / run = 1/4; y increases by 1 each time x increases by 4.
Thus, Answer B is the correct one: y = (1/4)x
