Find the y intercept for the equation -2x+2=4
Solve for x. This will give you a vertical line at whatever x value you get. Does it intersect the y axis? If not, there's no y-intercept.
Was your equation supposed to say
-2x + 2y = 4 ?
the way you have it, TutorCat is right, you have a vertical line which obviously does not cut the y-axis, since it is parallel to it.
in general, to get the y-intercept, let x=0 in your equation and solve for y.
To find the y-intercept, we need to determine the value of y when x equals 0.
Let's solve the equation step by step:
-2x + 2 = 4
First, subtract 2 from both sides of the equation:
-2x = 4 - 2
-2x = 2
Next, divide both sides of the equation by -2 to isolate x:
(-2x) / -2 = 2 / -2
x = -1
Now, we substitute this value of x into the equation to find y:
-2(-1) + 2 = y
Simplifying further:
2 + 2 = y
y = 4
Therefore, the y-intercept for the equation -2x + 2 = 4 is 4.
