The answer is (C) vertical asymptote.
Step-by-step explanation:
the general slope intercept formula is
y = ax + b
a is the slope of the line.
b is the y-intercept (the point, where the line crosses the y-axis, meaning the y value when x=0).
we get b by using the point coordinates in the equation and solve for b :
-2 = (1/4)×0 + b
b = -2 (as expected)
the full line equation is
y = (1/4)x - 2
Answer: B. No
Step-by-step explanation: Let's think of the variable x as apples. If there are 7 apples and then you added 1 other something, that would be different than having 1 apple and adding 7 other somethings. The equations would have a different amount of somethings and apples.
Answer:
y = -1
Step-by-step explanation:
Details have been given in the question, we need to break them apart and create our equations accordingly.
"the sum of two times x and 3 times y is 5"
2x + 3y = 5
"the sum of two times x and 3 times y is 5"
x - y = 5
So, our two equations are:
2x + 3y = 5
x - y = 5
Solve using substitution method, by moving y to the other side.
x = y + 5
2(y + 5) + 3y = 5
2y + 10 + 3y = 5
Combine like terms
5y + 10 = 5
Subtract 10 from both sides
5y = -5
y = -1
Step-by-step explanation:
Question 5
y = - 3x
