Solve the system by graphing.
2 answers:
Answer: Option A. The solution set is (4,5)
Step-by-step explanation:
Solve the equation for<em> </em>y to obtain the form of the equation of the line.
You have:
y=-x+9 (The slope is -1 and the y-intercept is 9)
y=x+1 (The slope is 1 and the y-intercept is 1)
When you graph it you obtain the graph shown in the figure attached.
The solution is the intersection of the lines.
Then, the solution set is (4,5)
Answer:
Choice A is correct answer.
(4,5)
Step-by-step explanation:
We have given a system of equations.
x+y = 9 eq(1)
x-y = -1 eq(2)
We have to solve given system of equations by graphing.
From eq(1) ,
y = -x+9
slope = -1 and y- intercept is 9.
Frpm eq(2) ,
y = x+1
slope = 1 and y-intercept = 1
We have to draw given equation on graph.
From attachment , see the intersection point of equations.
(4,5) is intersection point which is our solution.

Answer:
Part A)
The equation in the point-slope form is:
Part B)
The graph of the equation is attached below.
Step-by-step explanation:
Part A)
Given
- The point = (-2, 11)
- m = 4/3
The point-slope form of the line equation is
Here, m is the slope and (x₁, y₁) is the point
substituting the values m = 4/3 and the point (-2, 11) in the point-slope form of the line equation
Thus, the equation in the point-slope form is:
Part B)
As we have determined the point-slope form which passes through the point (-2, 11) and has a slope m = 4/3
The graph of the equation is attached below.
