The way to solve this is to solve one of the equations for x or y. The bottom one looks easier. x=32-5y Substitute that value into the top equation. -3(32-5y)+5y=44 -96+15y+5y=44 20y=140 y=7 Now substitute y into the bottom equation x+5(7)=32 x+35=32 x=-3 Now...

We need a line that is parallel to y=3/4x+1 that goes through (8,-10).  The formula for a line is y=mx+b  Since it is parallel to the given line we already know the slope or m is 3/4, we know the x is 8 and y is -10, we just need to find the y-intercept or b.  We can also...

Let's say that you have 20 apples, but you can't find anyone who wants them.  Mathematically, the answer would 20/0.  Dividing by zero is like saying that no one cares about the thing you are trying to divide.  If no one cares, why bother?   

This is telling you that a line that cross the coordinates (5,y) and (7,-9) has a slope of -4. To compute the slope, we use the formula rise over run.  The rise is (y -(-9)) and the run is (5-7).  Therefore, the slope formula is (y-(-9))/(5-7)=-4.  Now we solve for y. 1. ...
