A linear function. It is a horizontal line at -7.
y - |x| is an expression, not a function.
determine whether each relation is a function y equals -8
If you plug in y for the x function, and it equals the answer you got, it is right.
-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.
y - |x| is an expression, not a function.

Y = 2X + 8 is a linear function of the form, Y = mX + c. A line.
It is a linear function. That is to say, it is a function representing a straight line in the coordinate plane.
determine whether each relation is a function y equals -8
f(x) = 2x2 + 4x - 7
y = x This is a line and a function. Function values are y values.
Assuming that b > 0, it is an inverse power function or an inverse exponential function.
yees because if you divide everything by 8 to get y=7/8+3x/8 which is a linear function since it fits the equation y=mx+b
If y equals 7, then y equals 7. This equation is already in final, solved state. Read it out loud and you will understand.
