Which type of association is shown in this scatter plot? a. moderate and positive b. moderate and negative c. strong and negative d. strong and positive

Since we are not given the scatter plot, it would be hard to figure what is the correct association. My only option would be to discuss each of the option as much I could. Linear positive association would be depicted by a scatter plot with data that almost forms a straight line and sloping to the right upward. As the x increases, the y increases as well. Linear negative association would be the opposite of the linear positive. The plot would sloping upward to the left. As the x increases, the value of y would decrease. Nonlinear positive association would be almost the same as the linear positive however the data do not form a line. It may be form a curve. Nonlinear negative would be also almost the same as the linear negative only that the data do not form a line.

(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
