Answer:
Y= 4x-3
Step-by-step explanation:
The y-intercept is -3,
the slope is 4:
rise over run= 4/1 or 4
so 4x-3

Which expression is equivalent to -1.3 - (-1.9)−1.3−(−1.9)minus, 1, point, 3, minus, left parenthesis, minus, 1, point, 9, right
RideAnS [48]
Answer:
Choise B: 
Step-by-step explanation:
For this exercise you must remember the multiplication of signs:

By definition, equivalent expression have the same value.
Then, you can find an equivalent expression to the expression provided in the exercise by simplifying it.
So, given:

To simplify it, you can distribute the negative that is located outside of the parentheses (in order to eliminate the parentheses).
Applying this procedure, you get the following equivalent expression:

Therefore, as you can notice, the expression obtained matches with the one shown in Choice B.

tgH=HJ/HK
angle H+angle K=90
H=K=45 degree
sin45=cos46 = square root of 2/2
Answer:
4
Step-by-step explanation:
Ok.....Since I can't graph it, we can make a table
x y
3 9
1 1
From 9 to 1, you subtract 8 (this is for the y section)
From 3 to 1, you subtract 2 (this is for the x section)
Now all you have to do is divide the y with the x
y/x = 8/2 = 4
And 4 will be your slope for these two points.
Hope this helped!
