Error Analysis Your friend incorrectly makes this graph as an
example of a linear function with initial value - 2. What is your friend's
error? Find an example of a graph with initial value - 2.
What is your friend's error?
O A. The graph has rate of change - 2, not initial value - 2.
OB. The graph crosses the y-axis at y = 2 instead of at y = -2
OC. The graph has y-intercept - 2, not initial value - 2.

x = -2

y = 848

step-by-step explanation:

plug in the numbers

the balance is found at the link

step-by-step explanation:

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3

hi there!

the answer will be d: 2
