2x + y = 4 (let x = 0 to find the y-intercept)
2(0) + y = 4
0 + y = 4
y = 4
2x + y = 4 (let y = 0 to find the x-intercept)
2x + 0 = 4 (divide both sides by 2)
x = 2
2x + y = 4 (to obtain another point let x = 1 and find the corresponding y-value)
2(1) + y = 4
2 + y = 4 (subtract 2 from both sides)
y = 2
Plot the three points (0, 4), (1, 2), and (2, 0) in a coordinate plane, and draw a line that passes through these points.

How do you use a graphing calculator to solve quadratic equations?
Graph the equation then find the x intercepts.
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.
How do you determine the intercepts from an equation or graph?
From the equation, the y intercept is simply determined by setting x = 0. The x intercept(s) are generally much harder to find: you will need to find the solutions of y = 0 [or f(x) = 0]. From the graph the intercepts are the coordinates of the points at which the graph crosses the axes.
Find the intercepts for the graph of the equation given x plus 5y equals 0?
x + 5y = 0Subtract 5y from each side of the equation, just to put 'x' and 'y' on opposite sides.x = -5yThis is interesting. If EITHER 'x' OR 'y' is zero, then the other one is also zero.The only place on the graph where that is true is the origin. So the line goes through the origin,and the 'x' and 'y' intercepts are both zero.
How d yu find x and y intercept on a graph?
In the equation y = f(x), Put x = 0 and solve for y. Those are the y intercepts. Put y = 0 and solve for x. Those are the x intercepts.

How do you find the x and y-intercepts for the graph of the equation 6x-5y equals 60?
When y is 0 then x intercept is at (10, 0) When x is 0 then y intercept is at (0, -12)
How do you find the equation of a graph?

How do you graph y x 2?
It is a line. There are many ways to graph it using intercepts etc. But, you can pick some x points, plug them in your equation, and find the corresponding y point, The graph those (x,y) values
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.
