You can put this solution on YOUR website! Find the x-and y-intercepts of the line that passes through the given points.
(7,5),(4,1)
----------------------
slope: (5-1)/(7-4) = 4/3
-------------------------------
Form: y = mx + b
You know y = 1 when x = 4 and m = 4/3
-----------------------
1 = (4/3)4+b
b = 1-(16/3)
---
b = -13/3
-----------------
Equation:
y = (4/3)x-(13/3)
=====================

hahaWe are trying to find equation of form y=ax+b, where a is slope, and b is intercept, which passes through points (x1, y1) = (7, 5) and (x2, y2) = (4, 1).
Slope a is  .
Intercept is found from equation  , or  . From that,
intercept b is  , or  .
y=(1.33333333333333)x + (-4.33333333333333)
Your graph:

equation of the line is:
when  , 
so,  is (0, -4.3)
when  ,
 is (3.3,0)
