Find the equation

Question

Find the equation of the line that contains the point whose coordinates are (0, 0) and has slope 3/7

Answer 1

B = y - mx

= 0 - (3/7)(0)

= 0

y = mx + b

= (3/7)x + 0

= (3/7) x

Answer 2

The equation of a line is y=mx+b where m is the slope of the line and b is where the line crosses the y or vertical axis.

Since the coordinates are (0,0) you know that b is 0, the point where the line crosses the y or vertical axis, the slope is 3/7 so the formula is:

y=3/7x+0 or y=3/7x
