Answer:

#y=2x+4#

Explanation:

A linear equation has a standard form of:
#y=mx+c#

Where #m# is the gradient/slope and #c# denotes the y-intercept.

So a line which has a slope/gradient of 2 means that #m=2#, so we replace #m# with 2. Similarly, as it has a y-intercept of 4, means that #c=4#, so we replace #c# with 4 in our standard form-equation.

This yields the equation:

#y=2x+4#
