Answer:
y= 4x-6
Step-by-step explanation:
The equation of a line is usually written in the form of y=mx+c, where m is its gradient and c is its y-intercept.
Let's find the gradient, m, first.
Using the above formula,
Subst. the value of m into the equation.
y=4x+c
To find c, substitute a coordinate into the equation.
When x=0, y= -6,
-6= 4(0) +c
c= -6
Thus, the equation of the line is y= 4x -6.
