Question 1167929: Find the x-intercept of the graph of 4x - 2y = 8.
Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
the x intercept is the value of x when y = 0.
your equation is:
4x - 2y = 8
replace y with 0 to get:
4x - 2 * 0 = 8
simplify to get:
4x = 8
solve for x to get:
x = 8/4 = 2
the x-intercept is equal to 2.
the coordinate point where this occurs is (x,y) = (2,0).
here's a graph of the equation.
you can see that x = 2 when y = 0
some additional information.
the y-intercept is the value of y when x = 0.
when x = 0, 4x - 2y = 8 becomes 4 * 0 - 2y = 8.
simplify to get:
-2y = 8
solve for y to get:
y = 8 / -2 = -4
the coordinate point where this occurs is (x,y) = (0,-4)
both the x and y intercepts can be seen on the graph.
