Answer:
- B. The slope of the graph of k is 2.
Step-by-step explanation:
<h3>Find the equation of the line.</h3>
<u>The slope is:</u>
<u>The y-intercept is:</u>
<u>The line is:</u>
<h3>Now lets look at the answer options</h3>
A. <u>The x-Intercept of the graph of k is 8.</u>
- The x- intercept is -3, False
B. <u>The slope of the graph of k is 2.</u>
C. <u>The graph of k passes through (-1, -8).</u>
- -8 = 2(-1) + 6
- -8 = 4, False
D. <u>The zero of k is 3.</u>
- x = 0 ⇒ y = 0+ 6 = 6, False
Answer:
For numbers between 0.1 and 0.2, there is a 1 in the tenths' place: 0.11, 0.12, 0.13, and so on. For numbers between 0.2 and 0.3, there is a 2 in the tenths' place: 0.21, 0.22, 0.23, and so forth. For example, the number “seven and forty-two hundredths” can be written as 7.42.
