A line has slope 3 and y-intercept 4.

Which answer is the equation of the line?

y=3/4x-4

y = 3x + 4

y = 4x + 3

y=3x-4

answer b. y = 3x + 4

Step-by-step explanation:

y = ax + b

with a and b being as follows:

a = slope, which is given as 3.

b = the y-intercept meaning, where the line intercepts the y axis, which is given as 4.

Now you know the answer of the equation of the line, which is answer b. y = 3x + 4
