Answer:
Slope=5/7
Step-by-step explanation:
Slope=Δy/Δx=(3-(-2)) /(9-2)=5/7
Answer:
any line can be parallel to that as long as the y-intercepts are different and they contain the same slope which in this case, is 3.
Step-by-step explanation:
an example would be y = 3x + 4
It has no solution because it is not factorable
Let’s take fred age as x and Natalie’s age as y.
So,
A/Q
X + Y = 43. Let it be eqution 1
and
X + 4Y = 79. Let it be equation 2
Combining equation 1 and 2, we get
( X + Y) + 3Y = 79
43 + 3Y = 79
3Y = 36
Y = 12
Now, evaluating the value of Y in equation 1 we get,
X + 12 = 43
X = 31
Therefore, Fred is 31years old and Natalie is 12 years old.
