- Given the following system of equations and its graph below, what can be determined about the slopes and y-intercepts of the system of equations? 7 y 6 5 4 3 2 -6-5-4-3-2-1 1+ -2 1 2 3 4 5 6 x + 2y = 8 2x + 4y = 12 The slopes are different, and the y-intercepts are different. The slopes are different, and the y-intercepts are the same. The slopes are the same, and the y-intercepts are different. O The slopes are the same, and the y-intercepts are the same.arrow_forwardChoose the function to match the graph. -2- 0 -7 -8 -9 --10- |--11- -12- f(x) = log x + 5 f(x) = log x - 5 f(x) = log (x+5) f(x) = log (x-5) 9 10 11 12 13 14arrow_forwardWhich of the following represents the graph of f(x)=3x-2? 7 6 5 4 ++ + + -7-6-5-4-3-2-1 1 2 3 4 5 6 7 -2 3 -5 6 -7 96 7 5 4 O++ -7-6-5-4-3-2-1 -2 -3 -4 -5 -7 765 432 -7-6-5-4-3-2-1 -2 ++ -3 -4 -5 -6 2 3 4 5 6 7 7 6 2 345 67 -7-6-5-4-3-2-1 2 3 4 5 67 4 -5arrow_forward
