The y-intercept will occur where the x coordinate equals zero. Substituting x=0 into the equation, we have y - 0 = 7 --> y = 7, so the y-intercept is 7.

What is 2x-y equals 7 in y form?
-5
How do you simplify y equals 2x-5 and 4x-y equals 7?
y = 2x-5 4x-y = 7 => y = 4x-7 2x-5 = 4x-7 2x-4x = 5-7 -2x = -2 x = 1 Therefore by substituting: x = 1 and y = -3
What is the slope-intercept form of the equation -2x plus y equals 7?
y=2x+7. The 2 is your slope and the 7 is your y intercept.
Work out 2x equals y plus 7 and x-2 equals y simultaneous equation?
2x = y + 7 x - 2 = y substitute the y from the second equation into the first: 2x = x - 2 + 7 2x = x+5 x = 5 --> y = 5 - 2 y = 3
How do you rewrite this equation so that y is a function of x 2x plus y equals 7?
y=f(x)= x(2x+y)=7 f(x)=2x^2 +xy -7 = 0 y=2x^2 +xy -7 y-xy -7 + 2x^2 = 0 y(1-x)=2x^2-7 y=(2x^2-7) / (1-x) Excuse the working. Y equals 2 X squared minus 7 all divided by 1-X
Y equals 14 - 2x graph?

How do you solve y equals y equals 2x-1 y equals 5x-13?
y = 2x -1 y = 5x -13 So: 5x -13 = 2x -1 5x -2x = 13 -1 3x = 12 x = 4 and by substituting y = 7
Convert 2x-3y equals 7 to slope intercept form?
If 2x - 3y = 7, -3 y = 7 - 2x or y = (2x - 7)/3, or y = (2/3)x - (7/3). The slope is 2/3 and the y-intercept is -(7/3).
X plus y equals 8 2x equals y - 5?
x=1 y=7
X-y equals 8 and 2x plus y equals 7?
x=5 y=-3
What type of lines are these x plus 2y equals 7 and 2x - y equals 7?
x + 2y = 7 2y = -x + 7 y = -(x-7)/2 => -x/2 + 7/2 2x - y = 7 -y = -2x + 7 y = 2x + 7 Since -1/2 is the negative reciporical of 2, the slopes of these equations are perpendicular. Therefore, these two lines are perpendicular.
2x plus 3y equals 7 what is x and y?
X equals 1 and so does Y
