8x - 4y = 24 divide by 4 both sides
2x - y = 6
Let y = 0,
2x = 6
x = 3 so the x-intercept point is (3, 0)
Let x = 0,
-y = 6
y = -6 so the y-intercept point is (0, -6)

How to find the x-intercepts when there is no y?
If there is no y, then the equation is of the form x = c where c is some constant value. And so the line intercepts the x axis at (c,0).
Find the slope and intercepts of each line y equals -x plus 1000?
Slope: -1 intercepts: (0,1000),(1000,0)
When can finding the x and y intercepts help you graph a line more efficiently?
If it's a straight line, then that's all you need. Find the 'x' and 'y' intercepts,lay your ruler down between the two points, and draw your line.
Why do you need x intercepts for quadratic equations?
so you can find the solution for the x-values. the x-intercepts are when the graph crosses the x-axis
How do you find slope using x and y intercepts?
Your x and y intercepts give you two points on the line of the graph. Use these two points in the slope equation m = (y2-y1)/(x2-x1), and that gives you the slope.

What are x and y intercepts?
The x and y intercepts are where a line on a graph intersects (crosses over) the x or y axis.
Why do you need x intercepts for quadratic equations?
so you can find the solution for the x-values. the x-intercepts are when the graph crosses the x-axis
How would you use intercepts to find the vertex in a quadratic equation with two x intercepts?
The vertex must be half way between the two x intercepts
How do you find slope using x and y intercepts?
Your x and y intercepts give you two points on the line of the graph. Use these two points in the slope equation m = (y2-y1)/(x2-x1), and that gives you the slope.
How to find the slope to an equation?
If it is the equation for a line, then it can be rearranged into the format y = mx + b, where m is the slope of the line, and b is the point where the line intercepts the y-axis.If it is not for a straight line, then the slope is changing with x, and the derivative of the function would find the slope at a particular x.
How do you find the maximum height of a parabolic path?
If "a" is negative then the graph is a cap. Find the x intercepts. Average the two x intercepts and substitute that into the equation it will give you the y.
What is y equals -x using intercepts?
y = -xBoth intercepts are at the origin. From there, the line slopes up to the leftand down to the right.
What is the x-intercept for y equals 5x - 10?
-5
What if you cant do find the x intercepts?
Then there is no x-intercept. No big deal. Lots of functions do not have x- intercepts. For example, y = x2 + 1 or y = 2x
