Answer:

-2

Step-by-step explanation:

use the slope formula which is y2-21/x2-x1

these are what i chose my numbers to be

-4=x1

-1= y1

-2= x2

-5= y2

-5-(-1)/-2-(-4) = -2

thats all

2) What is a definition of a line that is parallel to XY?

Answer:

it's b

Step-by-step explanation:

parallel lines stay the same distance away from each other all the time. they could go on forever and would never cross. think of a parallelogram. the lines always stay the same width apart, like train tracks. this would mean that is is b because it does not intersect xy

What equation represents the line that passes through the points (-3 7 and (3 3?

dexar [7]

Hello : let A(-3,7) B(3,3)
the slope is : (YB - YA)/(XB -XA)
(3-7)/(3+3) = -2/3
an equation is : y=ax+b a is a slope

y = (-2/3)x +b

the line through point B (3,3) : 3 = (-2/3)(3)+b
b =5
the equation is : y =(-2/3)x+5

The final exam of a particular class makes up 40% of the final grade, and Moe is failing the class with an average (arithmetic m

amm1812

Answer:

%82.5

Step-by-step explanation:

The final exam of a particular class makes up 40% of the final grade
Moe is failing the class with an average (arithmetic mean) of 45% just before taking the final exam.

From point 1 we know that Moe´s grade just before taking the final exam represents 60% of the final grade. Then, using the information in the point 2 we can compute Moe´s final grade as follows:

$FG=0.40*FE+0.60*0.45$ ,

where FG is Moe´s Final Grade and FE is Moe´s final exam grade. Then,

$\frac{ FG-0.60*0.45}{0.40}=FE$ .

So, in order to receive the passing grade average of 60% for the class Moe needs to obtain in his exam:

$FE=\frac{ 0.60-0.60*0.45}{0.40}=0.825$

That is, he need al least %82.5 to obtain a passing grade.
