Answer: y=2x-2
Explanation:
y=mx+c is the format for the equation of a straight line.
m is the gradient
c is the y intercept
The line intercepts the y axis at (0,-2), so c must be -2.
The gradient is calculated by (change in y)/(change in x), which is 6/3 = 2, so m must be 2.
Therefore, after substituting these values, y=2x-2
