Answer:
the answer would be B
Step-by-step explanation:
for the slope you would need to count up then over between the two points and do that until you reach where the line crosses or in this case would cross for the y-intercept
Answer: devied the 2 numbers
Step-by-step explanation:
Answer:
Blue - y=-2
Red-![y=\frac{2}{3}x+2](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B2%7D%7B3%7Dx%2B2)
Parallel to Red-![y=\frac{2}{3}x+5](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B2%7D%7B3%7Dx%2B5)
Perpendicular to Red- ![y=\frac{-3}{2}x+2](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B-3%7D%7B2%7Dx%2B2)
Step-by-step explanation:
The slope intercept of a line is y=mx +b where
- m is the slope which is calculated as the vertical distance divided by the horizontal distance between two points.
- b is the y-intercept for value on the y-axis for which the line crosses it.
The Blue line intercepts the y-axis at -2 so b=-2. It has no vertical change since it is a horizontal line. This means the slope, m, is 0. m=0. It's equation is y=0x-2
y=0-2 since anything times 0 is 0.
y=-2.
The red line intercepts the y-axis at 2 so b=2. It intercepts the x-axis at (-3,0). Between these two intercepts we can find the slope:
Slope:
We substitute
and
The red line has equation
.
Parallel lines have the same slope with a different y-intercept. So we write a line where m=2/3 and b is something else.
![y=\frac{2}{3}x+5](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B2%7D%7B3%7Dx%2B5)
Perpendicular lines have a negative reciprocal slope to the original. So we write the line where m/-3/2.
![y=\frac{-3}{2}x+2](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B-3%7D%7B2%7Dx%2B2)

➷For #1 the shape is a trapezoid.
There are many ways to name it:
- trapezoid, because it has four sides and 1 set of parallel sides
- quadrilateral, because there are four sides
For question #2 the shape is a square
There are many ways to name it:
- square, because there are four equal sides and four right angles
- rectangle, because as square is a rectangle
- quadrilateral, because there are four sides
- parallelogram, because there are two pairs of parallel sides
- rhombus, because there are four equal sides
