Solve the following system of equations for z and for y: Value of 2 Value of y System of Equations: y=9+32 y=58 - 42 Solve the following system of equations for a and for b: Value of a Value of b System of Equations: 9a + 3b = 30 8a + 4b = 28 Plot the following system of equations on the following graph. System of Equations: p= 6 - 29 p=2+2 Note: Use the orange line (square symbols) to plot the first equation, and use the blue line (circle symbols) to plot the second equation. 10 7 9 p = 6 - 29 8 7 6 p= 2 + 9 5 4 3 2 1 0 + + 0 1 2 3 4 5 6 7 8 9 10 9 The values of p and q that solve these two equations simultaneously can be seen on the graph as the coordinates at which the two lines intersect
