Graph using two points; f(x)=−0.5x+3.

write a system of equations to model the situation. add the equations to eliminate the y-term and then solve for x. substitute the value for x into one of the original equations to find y. check your answer by substituting x = 8 and y = 2 into the original system.

to figure out if an ordered pair is a solution to an equation, you could perform a test. identify the x-value in the ordered pair and plug it into the equation. when you simplify, if the y-value you get is the same as the y-value in the ordered pair, then that ordered pair is indeed a solution to the equation.

i think that you should ask google for the answer to that problem because if we don't know it google does
