What is the equation of the following line? be sure to scroll down first to see all answer options.
a. y= 7x
b. y= 21x
c. y= -7x
d. y= -3x
e. y= 1/5x
f. y= 3x

The equation of a line is y = 7x .

Option (A) is correct .

Step-by-step explanation:

As the equation of the line in the form

y = mx + c

Where m is the slope and c is the y - intercept.

Thus

As shown in the figure the line pass through the point (0,0) and (1,7) .

Thus

m = 7

As the line passes through the origin, the y intercept is already determined (it is 0 since the line will pass through the y axis at 0).

Thus

c = 0

Put the value of m and c in the equation

y =  7x + 0

y = 7x

Therefore the equation of a line is y = 7x .

Option (A) is correct .
