Can someone me with my hwplz(only the circled ones)

What are the solutions of the system? solve by graphing. y = -x^2 -6x - 7 y = 2

Identify the slope an intercept of the following linear equation y = 1/5x - 6 a. slope: 1/5; intercept: -6 b. slope: 5; intercept: -6 c. slope: -1/5; intercept: 6 d. slope: 1/5; intercept: 6
