Question 1 Given a function described as equation y = 3x + 4, what is y when x is 1, 2 and 3?
A 7,8,9
B
3, 7, 11
C 3,6,9
7, 10, 13

Answers:

Step-by-step explanation:

To solve this, we plug in the given values for x, 1, 2, and 3.

y = 3x + 4

y = 3(1) + 4

y = 3 + 4

y = 7

y = 3x + 4

y = 3(2) + 4

y = 6 + 4

y = 10

y = 3x + 4

y = 3(3) + 4

y = 9 + 4

y = 13

Interesting pattern: y appears to be 3 times x

In other words: as x increases by 1, y will increase by 3. The slope of this line is y/x or 3/1 or simply, 3.

hi,

you half the rectangle that you ae asking about so then you would see the scale factor of 1/2 the one u have selected, the one on top is half.

hope this !
