880
Step-by-step explanation:
Answer:
Part 1) 
Part 2) The graph in the attached figure
Step-by-step explanation:
Part 1)
we know that
The linear equation in slope intercept form is equal to

where
m is the slope
b is the y-intercept
we have

substitute in the linear equation

solve for b

substitute

Part 2) Draw the equation
we know that
To graph a line we need two points
we have the y-intercept (0,4) and (2,-4)
Plot the points, connect them and join to draw the line
see the attached figure
Answer:
x = -1
Step-by-step explanation:
because both lines intersects at -1.
Answer:
D. 7n = 28
Step-by-step explanation:
Let's substitute 4 for n in each equation to check if it the resulting equation is correct:




Therefore the answer is D
I think its B because, the formation would be (x,y) so that means (5,-3)
