Question

A line has slope 3 and y-intercept 4.

Which answer is the equation of the line?
O y = 3x + 4
Oy= 3x -4.
O y= 3/4x-4
O y = 4x + 3

Answer 1

y = 3x +4

Explanation:

In slope-intercept form, the equation of a line is ...

y = mx + b

Where m is the slope (3) and b is the y-intercept (4).

Putting the given numbers in the equation, it becomes ...

y = 3x +4
