Answer:
A
Step-by-step explanation:
Those two lines are the same. If you divide the second equation by 2, you will end up with the first equation. A system of linear equations cannot have two of the same line.
Answer:
The difference between slope and y-intercept, is y-intercept is a specific point. Y-intercept is when the line crosses the y-axis, or when x = 0. Slope is how much the y value changes when the x has changed +1, or -1, if that makes sense.
I was gonna do an example, but I got lazy, hehe.
Answer:
2
Offmind's Step-by-step explanation:
The Mode of a data set (<em>line plot in this case</em>) is the number which occurs most often. The line plot here shows the most x's on the number 2 than any other number so the mode is in fact, 2.
Bonus Fact: In another case, if there had been two numbers with the same amount of x's then those would both be considered the mode!

Let “t” represent the number of minutes Martha exercises each day. If she needs to exercise *at least* 30 minutes, t has to be equal to or greater than 30, so our inequality would be
t ≥ 30
