What is the equation of the line that passes through (0,3) and (7,0)

Answer:

y = (-3/7)x + 3  

Step-by-step explanation:

As we go from (0,3) to (7,0), x increases by 7 from and y decreases by 3 to 0.

Thus, the slope of this line is m = rise / run = -3/7.

Subst. the appropriate values from this info into the slope-intercept form of the equation of a straight line:

y = (-3/7)x + 3                Note that the y-intercept is given:  (0,3).
