I posted my last question wrong.
1) The slope of a line is 3/4, the line passes through the point(4,7). Where does the line intersect the y-axis?
2) If x/y=z, and x*y*a=0, which of the following variables have to=0? Assume each of the variables is = to a different number.
3) simplify this expression (2x*2+4x-30)/(x-3)
4)the volume of a cookie jar would most likely be measured in: cubic feet or cubic inches or square millimeters or square centimeters
5) Rob know that his average in math class is 89%. However he can only recall four of the five test scores; 85, 92, 80, 90. What is his score on the fifth test?
6)There are kiwis, oranges and mangoes in a bowl. There are twice as many kiwis as there are oranges and half as many mangoes as there are oranges. There are 14 pieces of fruit, how many mangoes are there?
7)The line passes through (1,4) and (-5,-5) what is the slope of the line?
8)Sarah has a cell phone plan that = 500 minutes @ $49.99 per month. Each additional minute = $.07. She talked 850 minutes. How would you write an equation for this problem? C= cost and m= minutes:
these are the options: a)$49.99-$.07m=c or b)$$49.99+$.07=c or c)$49.99+ $.07m=c or d)$49.99= $.07m
e) there is not enough information given to write an equation

I want my answers checked
1)(0,0) ???
2)a=0, because x/y=z cannot = 0???
3)2(x+5)
4)I don't know how to write this equation
5)89+92+80+90+x=.89--85+92+80+90+x-((89/100))=0 I put x = -34611/100 = -346.110
6)I don't know how to write this equation
7) ?
8)I put c) $49.99 + $.07m=c
