What is the distance between points (1,9) and (-4,-1)?

Use the distance formula:

Distance = √((X2 - x1)^2 + (Y2-y1)^2)

Distance = √((-4 -1)^2 + (-1-9)^2)

Distance = √(25+100)

Distance = √125

Distance = 5√5 ( Exact) or 11.1803 as a decimal.

600,000,000,000, or 6e14

step-by-step explanation:

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
