I’m going to assume you know slope-intercept form. The work will be displayed below on my magnificent, college-ruled paper.
The answer to the question is 11/14
Answer:
(1) 2 (2) (-1/2,0) (3) (0,1)
Step-by-step explanation:
The slope of the line is the number times x. This equation is y=mx+b, where m is the slope and b is the y-intercept. In this case, m is 2, so we have our slope. The y-intercept is easy, as we already know it to be (0,1). The x-intercept is the point where the line hits x when y=0. To solve for the x-intercept, we set y to 0 and solve. We have 0=2x+1. First, we subtract 1 from both sides and get -1=2x. Next, to get x by itself, divide both sides by 2. Now we have -1/2=x. Now we have our x coordinate for our x-intercept. Because of this, we get (-1/2,0) as our x-intercept.
Answer:
Step-by-step explanation:
-356.1 + 258.6 = -97.5
Imagine a long timeline with 0 in the middle, on the left we have -356.1 and on the right we have 356.1. Adding numbers makes the timeline move right.
Starting from the left, add (+) 258.6 to the number (moving right along the timeline). As 356 is larger than 258, the scale does not reach 0 yet and therefore the number must be negative.
Using this logic, the answer is 97.5
