The points of the linear function on the graph would be (-2,0), (0,-6), (-3,3) and (1,-9). The slope intercept form is y=-3x-6. And the zero of the function is x=-2.
To find the graph, use the slope intercept equation and the points. The roots or “Zeros” are the x values where the graph intersects the x-axis. To find the roots (zeros), replace y with 0 and solve for X.
It's 93. simple calculate it by: (76+68+83+x)/4=80 then 73*5-(67+75+73+69)=x where x here is the grade needed to reach an av. of 80. 4 is the number of tests. *common answer*
