Its equation is ;

#### Explanation:

first you will find its gradient ( slope );

gradient =

*{I am applying the first one]*

gradient =

gradient =

**now put gradient , in this equation**

y = m*x + c

*{where m is gradient & c is y-intercept (where x is 0) }*

*{now put the value of y and x, either use first point or the second one i.e. (1, 3) or (-4, 1) }*

*{c is found now put m and c in the equation y = mx + c}*

*{you can put any two points and the answer will be the same}*

equation found...!
