Answer:
3: D - Undefined
4: A - 1
Step-by-step explanation:
For Question 3 your answer is D, undefined, because it does not have a slope, a slope is like a hill, but that just goes straight up, thus it is undefined.
For Question 4 your answer is A, 1, because it moves one digit to the right and then 1 digit up, Thus that is your answer.
Answer:
True, they may not be congruent
Step-by-step explanation:
A figure cannot be determined as congruent from three angles alone. In order for two shapes to be congruent, all corresponding parts must be congruent. This means all the sides and angles of the two shapes must be the same in order for the two shapes to be congruent. If we know all the angles are the same, the sides could still be different lengths, so this does not prove congruency.
Answer: No, it does not matter.
Step-by-step explanation:
In addition the order does not matter, this is because of the commutative property of the addition, that says that: A + B = B + A
and the associative property, that says that:
A + (B + C) = (A + B) + C
for example, if you have 4 chips and your friend gives you her 5 chips, now you have a total of 4 + 5 = 9 chips.
The case is the same if you have 5 chips and your friend gives you 4 chips, now you have 5 + 4 = 9 chips.
Other example is that:
5 chips + ( 2chips + 1 chip) = 5 chips + 3 chips = 8 chips
(5 chips + 2 chips) + 1 chip = 7 chips + 1 chip = 8 chips
You can see that the order does not matter.
Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and c the y- intercept )
(1)
Here m = 6 and b = - 2, then
y = 6x - 2
(2)
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Here m = - 2 and b = 5, then
y = - 2x + 5 ← equation in slope- intercept form
Add 2x to both sides
2x + y = 5 ← equation in standard form
(3)
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (6, - 13) and (x₂, y₂ ) = (- 4, - 3)
m = 
= 
= - 1 , then
y = - x + b ← is the partial equation
To find b substitute either of the 2 points into the partial equation
Using (- 4, - 3 ) , then
- 3 = 4 + b ⇒ b = - 3 - 4 = - 7
y = - x - 7 ← equation in slope- intercept form
Add x to both sides
x + y = - 7 ← equation in standard form
