The slope-intercept is most usefull
Well the answer options are a bit confusing but the steps are 1, 2, & 3.
Answer: The slope is 5
Step-by-step explanation:
You can calculate the slope of the line with this fomula:

Given the points (2,3) and (1,-2), you can identify that:

Now, the final step is to substitute these values into the formula
, getting that the slope of this line is:


Answer:
20%
Step-by-step explanation:
To find the decimal answer, we just do 5/25 which is equivalent to 0.2
Then, we multiply 0.2 by 100 to get the percentage:
0.2*100=20
Answer:
Step-by-step explanation:
16. 180=8x+2x
x=10°
17a. 180=(180-126)+2x+(180-6x)
x=14°
17b. 180=4x+x+65
x=23°
