Answer: These are some points of the grahp:
(-2,4)
(0, 3)
(2, 2)
Explanation:
1) f(x) = -0.5x + 3, is the equation of the form y = mx + b
2) y = mx + b is slope-intercept equation of a line where the slope is m and the y-intercept is b, so, f(x) = - 0.5x + b has slope m = -0.5 and y-intercept b = 3.
3) To graph f(x) = -0.5x + 3, follow these steps:
- draw two perpedicular axis: vertical axis, labeled y, and horizontal axis, labeled x.
- draw marks on each axis, each mark equivalent to one unit.
- the intersection point of the vertical and horizontal axis is the origin, i.e. point (0,0).
- you can make a table with two or more points:
x f(x) = - 0.5x + 3
-2 4
0 3
2 2
4 1
6 0
4) You can see the graph in the figure attached, and select any of the points on the line either by using the table or by using the equation f(x) = -0.5x + 3.
Answer:
(A)A coordinate plane with a line starting at (negative 2, negative 4), passing through (0, negative 2) and (2, 1).
Step-by-step explanation:
Given the line: y=x-2
Comparing with the slope-intercept form y=mx+b
- Slope, m=1
- y-intercept is -2.
Therefore, the point (0,-2) must be on the line.
Only Options A and D have this point.
We then determine which has a slope, m=1.
<u>Option A</u>
Using points (-2,-4) and (0,-2)
Slope,
<u>Option D</u>
Using points (-3,0) and (0,-2)
Slope,
Therefore, Option A satisfy the requirements.
