Yes. y + x = 4 is a linear function because the highest order (exponent) on any dependent or independent variable is 1. So if it were y^2 + x = 4 or y + x^3 = 4 or yx + 4 = 0 or anything like that, it would be non-linear. If that doesn't help, if you rearrange y + x = 4 into standard y = mx + b format you get y = -x + 4. So it's a straight line with a slope of -1 and y-intercept of 4. Any time you have an equation that just has the letters in it (x, y, z, etc. any letter) without any exponents, it's a linear equation.

What is the linear equation for y equals x plus 4?
y=x+4
What is p plus 4 equals 15?
It is a linear equation in one variable, p.
Is the equation x plus y equals 4 linear or not?
It is linear. The highest power is 1 (x = x1, y = y1) so it is linear.
What is y equals -02 equals x squared plus x plus 4?
Two equations: a linear one in y and a quadratic in x.
Is y equals 2x plus 4 a function?
Yes.
Is 5xy plus 4 equals 9 linear or nonlinear?
5xy+4=9
What is the linear equation for y equals x plus 4?
y=x+4
What is z plus 37 equals 37 plus 4?
It is a linear equation in the variable z.
Is 5xy plus 4 equals 9 collinear or non collinear?
colinear and non-colinear are terms that are used when describing points in space, not the graph of a function. Maybe what you meant is "Is the function linear?" The answer to that question is no.
Is 8t plus 4 equals 76 an equation?
Yes, a linear equation in t.
Is four y squared plus nine equals 4 a linear equation?
No, it is not.No, it is not.
What is p plus 4 equals 15?
It is a linear equation in one variable, p.
Is the equation x plus y equals 4 linear or not?
It is linear. The highest power is 1 (x = x1, y = y1) so it is linear.
What is y equals -02 equals x squared plus x plus 4?
Two equations: a linear one in y and a quadratic in x.
Is x plus y equals 4 a function?
Yes.
Is y equals 2x plus 4 a function?
Yes.
Is 2y equals 8 a linear function?
Yes, 2y = 8 is a linear function. 2y = 8 is the same as y=8/2, or y=4, which is a vertical line.
