If slope of a line is 4 and y-intercept made by the line is 2 then the equation of line will be __________

Correct option is (a)
Given slope of the line (m) = 4 and y intercept of the line (c) is 2..
The general equation of slope intercept form is y=mx+c
putting m=4 and c=2 in the general equation
y=4x+2
the resultant equation will be y=4x+2

If slope of a line is 4 and y-intercept made by the line is 2 then the equation of line will be __________
