The x-intercept is found when y=0
Therefore 5x - (2 x 0) = 20 : 5x = 20 : x = 20/5 = 4.
-3
Yes.
x = 3, y = 3
Linear.
It is linear.
This is non-linear
Linear because neither of the variables are raised to a power.
no, because xx=x squared, and x squared is not linear
1/3 or .3333333333
-1
A linear equation has no higher powers than 1. This is linear.
Yes it is linear, it is a horazontal line, or 0 slope
