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:
-3/5
Step-by-step explanation:
you can use the formula to find the slope of a line when given two points.
we are given both the x and y intercepts, and we can use those in the formula.
the x intercept is (5,0) and the y intercept is (0,3)
i will treat (5,0) as my x1 and y1, and (0,3) as my x2 and y2
= -3/5
the slope is -3/5
