Answer:
<h2>y = 3x + 3</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:
m - slope
b - y-intercept
The formula of a slope:
==============================================
From the table we have :
x = 1 → y = 6
x = 2 → y = 9
x = 3 → y = 12
x = 4 → y = 15
Calculate the slope (choice any two pairs, and calculate the slope):
(1, 6), (2, 9)
We have the equation:
Put the coordinates of the point (1, 6) to the equation, and solve it for b:
<em>subtract 3 from both sides</em>
Finally:
Answer:
B
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
If y = log x is the basic function, let's see the transformation rule(s):
Then,
1. y = log (x-a) is the original shifted a units to the right.
2. y = log x + b is the original shifted b units up
Hence, from the equation, we can say that this graph is:
** 2 units shifted right (with respect to original), and
** 10 units shifted up (with respect to original)
<u><em>only, left or right shift affects vertical asymptotes.</em></u>
Since, the graph of y = log x has x = 0 as the vertical asymptote and the transformed graph is shifted 2 units right (to x = 2), x = 2 is the new vertical asymptote.
Answer choice D is right.
Answer: A
Step-by-step explanation:
The shape in the diagram is a square, a square is a shape with all sides being equal. To find out the length of all the sides, just count how many units make up one side since they're the same.
