Question

What is the y-intercept of the line with the equation y = 4 x + 2?

a. -2
b. 4
c. 2
d. -1/2

Answer 1

2

Explanation:

We need to find out the y intercept of the given equation which is y = 4x + 2 .

y intercept is a point where the graph of the equation cuts the y axis. So at y intercept x coordinate will be 0 , so plug in x = 0 , in the given equation as ;

y = 4x + 2

y = 4(0) + 2

y = 0 + 2

y = 2

Therefore the y intercept of the line is 2 . ( option C )

Answer 2

• C. 2

-----------------------------------

The y-intercept is the point where the line crosses the y-axis, which occurs when x = 0.

To find the y-intercept, substitute 0 for x in the equation y = 4x + 2:

• y = 4*0 + 2
• y = 2

The y-intercept is 2 and matching choice is C.
