We are given the following function
[tex]y=-3x+1_{}[/tex]We are asked to find the output y when the input x is 10
Simply substitute x = 10 into the function and solve for y
[tex]\begin{gathered} y=-3x+1_{} \\ y=-3(10)+1_{} \\ y=-30+1_{} \\ y=-29 \end{gathered}[/tex]Therefore, the output y is -29 when the input x is 10
