Can you me with these two questions?

For this question you are required to determine what is called a slope and y-intercept. To thoroughly explain, a slope is a constant factor while a y intercept is simply a number on the y-axis, for instance (0,1)

In order to determine slope, you would take two ordered pairs  and use the following y2 - y1 divided by x2 - x1 to determine slope.

On the first attachment, take two ordered pairs.

-1 - (-3) divided by 1-0

2/1 = 2

m = 2

On the second attachment, use a principle called rise over run to determine the slope.

Using the method above, we “rise” two boxes and “run” one box, therefore the slope for the second attachment would be 2 and if we go down 2 we determine that the y-intercept is 0

Applying the explanation, we determine for the first attachment that the most sufficient answer is y = 2x - 3

The answer for the second attachment is y = 2x

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.

the 3rd option is right
