To find the x intercept of an equation, simply plug in 0 for the y value, and solve for x (at the point where the line crosses the x axis, y will be equal to 0).
Ex/
2y + 3x = 21
3x = -2y + 21 (move y to opposite side)
3x = -2(0) + 21 (plug in 0 for y)
3x = 0 + 21 (multiply)
3x = 21 (add 0 and 21)
x = 7 (divide both sides by 3 to be left with only an x)
For this line, the point where the line intercepts the x axis is (7,0).

How do you find x intercept?
to find the y-intercept you plug in your x and y values in to the equation of y=mx+b. b is the y intercept and m is the slope. To find the x-intercept, set y = 0, and find value of x that satisfies the equation. If it is a line in the form y=mx+b, then the x-intercept will be at x= -b/m
How do you find the equation for Y intercept?
On the y-axis, x=0. Take the equation you have, set x=0, solve what's left for 'y'. That's the y-intercept.
How would you find the equation of a line if you were given the slope and the y-intercept?
y = {slope}x + {y intercept}
How do you find the coordinates of y-intercept and x-intercept on a graph?
You can either measure or estimate the coordinates visually from the graph, or solve the equation underlying the graph.
How do you find the x and y-intercept of the line for the equation 2x 3y-18?
2x = 3y - 18At the x-intercept, y = 0 :2x = -18x = -9At the y-intercept, x = 0 :3y - 18 = 03y = 18y = 6
How do you find x-intercept?
To find the x-intercept you need to set y=0 in your equation. To find the y-intercept you need to set x=0 in your equation.
How do you find the x intercept on a linear equation?
At the x-intercept on the graph of the equation, y=0. Take the equation, set 'y' equal to zero, and solve the equation for 'x'. The number you get is the x-intercept.
How do you find the equation of a line with the x and y intercept?
If the x intercept is a and the y intercept is b, then the equation of the line is bx + ay = ab
What is the x-intercept of a linear equation?
The x-intercept is where the line intersects with, or crosses, the x axis. To find it, take the equation, put in 0 for y, and solve for x. The intercept will be (#,0).
How do you find x intercept?
to find the y-intercept you plug in your x and y values in to the equation of y=mx+b. b is the y intercept and m is the slope. To find the x-intercept, set y = 0, and find value of x that satisfies the equation. If it is a line in the form y=mx+b, then the x-intercept will be at x= -b/m
What is the x intercept of 2xx?
The x-intercept is 0. To find the x-intercept of any equation, simply make y = 0 and then solve for x.
How do you find the x intercept of 2x - 3y?
-1
How do you find the magnitude of the y-intercept?
-- In the equation of the graph, set x=0. -- Solve the equation for 'y'. -- The value you get for 'y' when x=0 is the y-intercept.
How do you find the x and y-intercepts without using a graph?
-- Take the equation. -- Say to yourself, "At the x-intercept, y=0". Set 'y' equal to zero, solve the equation for 'x', and you have the x-intercept. -- Take the original equation again. -- Say to yourself, "At the y-intercept, x=0". Set 'x' equal to zero, solve the equation for 'y', and you have the y-intercept.
How do you find the x and y intercfept?
Set x = 0 and solve the resulting equation in y for the y-intercept. Set y = 0 and solve the resulting equation in x for the x-intercept.
How do you find y intercept?
Put x = 0 in the equation for y in terms of x.
