Answer:

Step-by-step explanation:
<u>Slope-intercept </u><u>form</u>
y= mx +c, where m is the slope and c is the y-intercept.

Slope




Substitute m= ⅕ into the equation:
y= ⅕x +c
To find the value of c, substitute a pair of coordinates.
When x= 10, y= 4,
4= ⅕(10) +c
4= 2 +c
c= 4 -2
c= 2
Thus, the equation of the line is y= ⅕x +2.
