If you are asking for the equation of the line, then:
Linear equation of a straight line has the general formula:
y = mx + c
where m is the slope and c is the y-intercept.
We are given that:
the slope (m) = 4
the y-intercept (c) = -2
Substitute with the givens to get the equation of the line as follows:
y = mx + c
y = 4x - 2
