Please help!!!!

hartnn · Answer

when slopes are equal, lines are either parallel or co-incidental!

Do you know what the slope of a line means?

hartnn · Answer

to find out which, we need to find the equation of line, do you know how to get it ?

anonymous · Answer

yes

hartnn · Answer

so what equation of line you got ?

mathstudent55 · Answer

Slope is a measure of the inclination of a line.
A zero slope means a horizontal line.
An undefined slope means a vertical line.
A positive slope means a line that goes up to the right.
A negative slope means a line that goes down to the right.

mathstudent55 · Answer

When you write the equation of a line in the form 

y = mx + b,

you can read the slope directly because m is the slope.

mathstudent55 · Answer

In your case, you were simply given the slopes of the two lines as 1.
That means they both go up to the right since the slope 1 is a positive number.
In  addition, the slopes are the same number, 1, which means the inclination (steepness) is the same.

The final piece of information is the points the two lines go through.
