How do you find the x and y intercept and middle point of y equals 2x plus 1?

To find the x-intercept, set y equal to zero (because that is where the line crosses the x-axis) and solve for x:
y = 2x + 1
0 = 2x + 1
-2x = 1
x = -1/2
To find the y-intercept, set x equal to zero and solve for y:
y = 2x + 1
y = 2*0 + 1
y = 1
The graph of this equation is a straight line that extends infinitely in both directions, therefore there is no "middle point."

How do you find the y intercept in slope intercept form if the slope is 2 and the equation y equals 2x plus b help me please?
y = 2x + b to find y-intercept, you should know one point. you put the point into x and y. and you can find y-intercept. if you are still confused, i want you to follow the related link that explains the concept of slope intercept form very clearly.
What is the y-intercept of this equation y equals 2x plus 5?
The y-intercept is the point where the line hits the y-axis when graphed. In order for a point to be on the y-axis, the x-value must equal zero. Therefore, substitute zero for "x" in the equation to find the y-intercept. y-intercept = (2)(0) + 5 y-intercept = 5
Find the intercept y equals x plus 4?
y=x+4 is the equation of a line in slope intercept form. This tells us 4 is the y intercept.The point (0,4) is actually the point where the line intersects the y axis. To find where it intersects the x axis just let y=0. The means x=-4 is the x intercept. So the point (-4,0)
How do you find the y-intercept and x-intercept of y equals -1?
The function y = -1 has no x-intercept; its graph is a horizontal line with a y-intercept of -1.
Find the coordinates of the x-intercept -x -2 y equals 6?
x-intercept = (-6, 0)

The function y = -1 has no x-intercept; its graph is a horizontal line with a y-intercept of -1.
How do you find the intercepts of 4y-12 equals 4x?
To find the y-intercept you substitute in 0 for x and solve. To find the x- intercept you substitute in 0 for y and solve. If you do it correctly you should find the x-intercept to be -3 and the y-intercept to be 3.
How do you find the slope and y-intercept of y equals 31x plus 4?
slope = 31 and intercept = 4
Find the coordinates of the x-intercept -x -2 y equals 6?
x-intercept = (-6, 0)
Find the coordinates of the x intercept x plus 5y equals 15?
The x-intercept is (15 0)
Find the x and y intercept for -3x plus y equals 13?
x intercept: -4 1/3 y intercept: 13
How do you find the y-intercept for y equals -3?
The equation of this line might be more familiar to you if you write it asY = zero(X) - 3Now you can see that the line has a slope of zero (it's horizontal) and passesthrough the point [ Y = -3 ] on the y-axis. That point is the y-intercept.
How do you find the y intercept in y equals mx plus b?
At the y-intercept, x=0 and y = b .
