Answer:
y = -3x - 1
Step-by-step explanation:
y = mx + c
m = (-4-2)/(1-(-1)) = -6/2 = -3
y = -3x + c
When x = -1, y = 2
2 = -3(-1) + c
c = 2 - 3 = -1
y = -3x - 1
The first one is a dashed line and the second one is solid. Two points for the first one is (1,4) and (0,3). For the second one two points are (0,-3) and (1,0). From build the lines. Finally the first one is where y is greater so shade above the line with points like ( 10,10) or (7,8) in the shaded region. For the second one since y is less or equal to shade below the line with points like (-2,-10) or (-1,-5).
A secant of a curve is a line that intersects the curve at a minimum of two distinct points.
So the answer is D. XY
The slope of this graph is - 4
Step-by-step explanation:
The slope of a line is
, where
and
are two points on the line- The slope of a horizontal line is zero
- The slope of a vertical line is undefined
∵ The graph is a line
∵ The line passes through points (1 , -2) and (0 , 2)
∴
= 1 and
= 0
∴
= -2 and
= 2
- Substitute these values in the rule below
∵ ![m=\frac{y_{2}-y_{1}}{x_{2}-x_{2}}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_%7B2%7D%7D)
∴ ![m=\frac{2--2}{0-1}=\frac{4}{-1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B2--2%7D%7B0-1%7D%3D%5Cfrac%7B4%7D%7B-1%7D)
∴ m = - 4
The slope of this graph is - 4

Answer: You might need to be more descriptive, there's a lot of numbers that could be added together to equal -8.
-4 + -4 = -8.
-6 + -2 = -8.
etc.
