Answer:
A linear equation is of the form:
y = a*x + b
Where a and b are real numbers, and we only have one term with x, and no powers of x larger than 1.
Let's rearrange all the given options to see if they take this form. I will isolate x for all of them.
a) 2x + 5y = 13
5y = -2*x + 13
y = (-2/5)*x + 13/5
(this is a linear equation)
b) -x^2 = 3y + 10
-3*y = x^2 + 10
y = (-1/3)*x^2 + 10/3
(this is not a linear equation)
c) 3(2x + y) = 14
6x + 3y = 14
3y = 14 - 6x
y = (-6/3)*x + 14/3
(this is a linear equation)
d) y = 13 - 2*x^2
(this is not a linear equation, we have a x^2 there)
e) 2 = y + x^5
-y = x^5 - 2
(this is not a linear equation, we have a x^5 there)
f) y = x + 7
we can rewrite this as:
y = 1*x + 7
(this is a linear equation)
