Answer:
Perimeter = 14
Area = 
Step-by-step explanation:
Substitute x=0 in the equation and find the value for y that makes the resulting equation true. For example, in the equation x-2y=2, when x=0, the equation becomes -2y=2. Since y=-1 makes this equation true, one point on the line is (0,-1)
1. Vertex: f(x)=x^2+2x+3
=> a=1 b=2
=> x=-2/2*1 => x=-2/2
=> x=-1
=> (-1,2)
2. Axis of symmetry: x=-1
Answer: 9/11
Step-by-step explanation: (8,0) (-3, 9). Subtract x values, subtract y values. This is known as delta x and delta y. Slope is rise/run. When you subtract the two points, you are finding the different between them. You're able to plug these x values and y values into an equation and get the correct answer. If you substitute x in, you get y. If you substitute y in, you get x (if you simplify it to get x on one side). So, the change is y is on the top, and change in x is on the bottom. 9 is divided by 11. This is the slope. You can plot this point by rising 9 and running (x axis) 11.
