Answer:
y = x y y = x-15 will be parallel lines
Step-by-step explanation:
It is called linear equation or first degree equation, a raised equality that involves the presence of one or more variables that are only raised to the first power (that is, the exponent of the variables is one).
The pending-ordered form at the origin of the linear equations in the case of having two variables is:
y=m*x+b
where "x" e "y" are the variables, m is the slope and b is the intersection with the axis "y", also called ordered to the origin.
This type of equation graphically represents a line.
In this case you have the following equations:
- y=x
- y=x-15
When comparing with the equation of a line, you can observe the values of the slope and the ordinate, which in each case are the following:
- m=1; b=0
- m=1; -15
On the other hand, parallel lines are those lines that are in the same plane and never intersect. That is to say that despite prolonging their trajectory to infinity, they never meet or touch at any point; they have no common point. For two lines to be parallel, it must be fulfilled that the lines have the same and different slopes ordered at the origin.
Note that this is what happened in this case: in both lines the slope is 1; but in the case of y = x the ordinate is 0 and in y = x-15 the ordinate is -15. This means that two parallel lines will be graphically observed. You can see this in the attached image.

You are essentially asking at this point where is the quadratic function greater than 0. To get the interval find the roots. Between the roots the function is guaranteed to be LESS THAN zero. Everywhere else the function is greater than 0.
Use Vieta's rule to get the roots,
Both roots are the same so no value is less than 0 which means all values except at the point of root are strictly greater, the point of root is at which means the set for which the quadratic function is greater than 0 is
"all real numbers except 1".
To convert this into interval notation use all numbers up to 1 but not including and all numbers after 1 but not including,
Hope this helps :)
