Answer:
No
Step-by-step explanation:
6 time 180 is only 108
108<120
There is not enough chalk.
Answer:
See below.
Step-by-step explanation:
So we started off with the equation:

And we subtracted x from both sides to acquire:

Now, this is essentially slope-intercept form. Recall that the slope-intercept form is:

Where m is the slope and b is the y-intercept.
If we rearrange our equation:

And put some parentheses:

We can see that this is indeed slope-intercept form.
And we can see that m is -1 and b is 2.
In other words, the slope is -1 and the y-intercept is 2.
Answer:
slope of line ax + by = c is -a/b
so, slope of 7x +2y =5 is -7/2
