Answer:
y= 6x -8
Step-by-step explanation:
<u>Slope-intercept form: </u>
y= mx +c, where m is the gradient and c is the y-intercept.
Gradient
= 6
y= 6x +c
To find the value of c, substitute the equation with a pair of coordinates.
When x= 1, y= -2,
-2= 6(1) +c
c= -2 -6 <em>(</em><em>-6</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
c= -8
Thus, the equation of the line is y= 6x -8.
