Answer:

y= -5x +22

Explanation:

Slope-intercept form

y= mx +c, where m is the slope and c is the y-intercept.


\boxed{slope = (y1 - y2)/(x1 - x2) }


slope = (2 - ( - 8))/(4 - 6)


m = (2 + 8)/( - 2)


m = (10)/( - 2)


m = - 5

y= -5x +c

To find the value of c, substitute a pair of coordinates into the equation.

When x= 4, y= 2,

2= -5(4) +c

2= -20 +c

c= 2 +20

c= 22

Thus, the equation of the line is y= -5x +22.
