That ordered pair is a solution to the equation system.
Each angle is 90 degrees because 90 times 3 is 270.
To find the x-intercepts algebraically, we let y = 0 y=0 y=0 in the equation and then solve for values of x. In the same manner, to find for y-intercepts algebraically, we let x = 0 x=0 x=0 in the equation and then solve for y.
Multiply your length value by 2.54. One inch is equal to roughly 2.54 centimeters,
Its 20.32 cm btw.
