How does the value of b affect the graph of the equation?
slamgirl [31]
Hey there!
B in a slope intercept form equation is the the y intercept. It dictates where the line will cross the y axis, and therefore the line's placement altogether. This is because if there was no y intercept, the line would only be shaped by the slope, and would start at 0.

How many solutions does this system have?
marissa [1.9K]

Answer:

No solution.

Step-by-step explanation:

Let us approach this question geometrically . Number of solutions is the number of meeting points of the two graphs . We can see that the given equations are equations of lines . First equation is 5x - y = 3.

Second equation when divided by two can be written as 5x - y = -1.

We can see that these lines are parallel and therefore doesn't intersect.So no solution.

As used in line 49, "take the slightest interest in"
MrMuchimi

Correct option is D. It means have curiosity about.

<h3>The line in passage is: line 49: </h3>

No one but a Swedish madman could take the slightest interest in it. Here I am.

In second paragraph, the narrator states that the North Pole “is an abstraction, a mathematical fiction" and that “no one but a Swedish mad man could take the slightest interest in it". In this context, the narrator is stating that people would not “take the slightest interest in,” or be curious about, the North Pole. So, option D best befits the context here. A, B, and C are incorrect because in this context, “take the slightest interest in" does not mean to accept responsibility, possess little regard, or pay no attention to something.
