Answer:
Step-by-step explanation:
To find the slope from two points you can use the following formula:
Now substitute the two sets of points
Substitute the values like this:
and
Now you will need to simplify the following expression:
Make sure that denominators are the same before substracting:
when you divide with a fractional number you only need to flip the second fraction over (find its reciprocal). Then just multiply:
M = 1 - 2 / 3 - 1
m = - 1 / 2
Answer: a-b+c+d =4
Step-by-step explanation:
The given system of equation is

from this we have the following matrices

the given matrix A =
On comparing Matrix
with Matrix A

we have the following values
a=2 ,b=4,c=8,d=-2
Thus a-b+c+d =2-4+8+(-2)=4
The problem ask to choose among the following functions in the given choices that has the greatest value and the best answer among the following function is letter D. a linear function that goes through point 2,0 and point 0,2. I hope you are satisfied with my answer
If its a reflection across the y axis the x value is reflected and the y value stays the same, so (-3,7)
