At -7.
If you mean y = 23x -2 then it is a straight line equation whereas 23 is the slope and -2 is the y intercept
youranswer would be -23x+y=-253 because you add 23x to both sides (to y and itself)
If you mean y = 23x-7 then the slope is 23 and the y intercept is -7
non linear
Linear means in order Non-Linear means Organic
No a linear equation are not the same as a linear function. The linear function is written as Ax+By=C. The linear equation is f{x}=m+b.
It is linear
A line is linear.
It is linear.
A linear objective function and linear constraints.
You can decide from a graph wheter a ralationship is linear or non linear if the line is staight is linear but if the line is not straight is not linear.
