Answer:
I think the constant is 2.
Step-by-step explanation:
5 is coefficient because it is with a variable. So 5 cannot be constant.
is slope-intercept form, which is a way of writing an equation for a line.
In this equation, 
represents the slope and 
represents the y-intercept.
and 
are the coordinates of a point on the resulting line.
Here are some examples:
Multiply both sides by 2.
2m = a + b
Subtract both sides by b.
2m - b = a
Answer:
1/2 (-sin2x - cos 2x)
Step-by-step explanation:
Distribute 1/2 to every term in the parentheses
