To graph y = -cosx,
a. shift y = cosx left 1 on the x-axis
b. shift y = cosx up 1 on the y-axis
c. reflect y = cosx over the x-axis
d. reflect y = cosx over the y-axis

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system

answer: #1 ads up by 8 and i don't know #2

b if for most of the graph

d if y intercept
