8x-4y=24, 2x-y=6, y=2x-6
so, 4x-6(2x-6)=28
x=1
y=-4

Find the the slope of the line passing through points 2,2 and -1,0

scZoUnD [109]

For a given function, slope is defined as the change in outputs, or y-values divided by the change in inputs, or x-values. In essence the slope asks "For a given change in x, how much does y change?" or even more simply: "How steep is the graph of this function?". This can be represented mathematically by the formula: $slope=m=\frac{rise}{run}=\frac{\Delta y}{\Delta x}-\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Substituting our known vlaues we have:
$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$
$m=\frac{2-0}{2-(-1)}$
$m=\frac{2}{3}$

What is the slope?

insens350 [35]

Answer:

3/4 or .75

Step-by-step explanation:

find two sets of coordinates on the grid. I choose 60,40 and 20,10. then first you subtract the y coordinates so 40 -10 which is 30 next you subtract the x coordinates so 60-20 which is 40 so your fraction is 30/40 which simplifies to 3/4 which as a decimal is .75
