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:
$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$
$m=\frac{2-0}{2-(-1)}$
$m=\frac{2}{3}$

Richard Saltwood’s car averages 620 miles on its 20-gallon tank of gas. If Richard runs out of gas and a mechanic comes to his r

grandymaker [24]

Well first you have to divide 620/20 which is 31. So his car goes 31 miles per gallon so you have 2 gallons and .25 of a gallon. So first off 2*31=62 miles then the 1/4 or .25. Multiply the 31 by .25 which is 7.75 now add 62 and 7.75 and you get how far his car can go.

62+7.75=69.75 miles
