Question 1099053: can you help me solve this linear functions equation? Emma charges a flat fee of $6, plus $8 per hour. Write an equation for the cost, C, after h hours of babysitting. what would be the slope and the x-intercept. I need to find out the x-intercept, how to make a table, range and domain, and mapping. thank you

You can put this solution on YOUR website!
The equation is:
+C+=+8h+%2B+6+
-------------------
This equation is in the general form:
+y+=+m%2Ax+%2B+b+
+m+ = slope
+b+ = the y-intercept
Note that +C+ is plotted on the vertical axis
and +h+ is plotted on the horizontal axis
-------------------------------------
The slope is +m+=+8+
The h-intercept is found by setting +C+=+0+, so
+0+=+8h+%2B+6+
+8h+=+-6+
+h+=+-3%2F4+ is the h-intercept
-----------------------------------------
The domain is minus infinity to plus infinity
You could say that the domain is zero to plus infinity
because Emma can't charge for less than zero hours
of babysitting
------------------------------------------------
The range would be 6 <= C <= plus infinity
She does not charge less than $6 ( zero hrs worked )
Also she can work any number of hours she wants up to infinity
---------------------------------------------------------
Hope this helps
