Question

Select the correct answer. What are the intercepts of y = 4x − 2?

Answer 1

Answer:

A  is the correct answer

Step-by-step explanation:

To answer this you need to find the value for x that makes the y value zero.

and the value for y when x is zero.

There are 2 intercepts on for a linear equation.  One x-intercept (where the graph crosses the x-axis) and one y-intercept (where the graph crosses the y-axis).

Step 1:  

The x-intercept is found by setting 'y' equal to zero and solving the equation.

0 = 4x - 2         solve this...

  2 = 4x            (add 2 to both sides)

0.5 = x                (divide both sides by 4 to get x by itself)

So the x-intercept is at the point (0.5. 0)

Step 2:  The y-intercept if found by setting 'x' equal to zero and solving

y = (0)x - 2  

   

   y = -2        

So the y-intercept is at the point (0, -2)
