Question

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 1

answer b. y = 3x + 4

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
