Question

Hi please answer and you dont NEED to show work but if u do i will give brainliest

Answer 1

Answer:

$y=-\frac{2}{5} -1$

Step-by-step explanation:

So first thing is that slope intercept form is setup like this

y=mx+b

m=slope

b=y intercept

the slope is change in y over change in x

as y goes down 2 x goes up 5

so the slope is -2/5

the y intercept is at (0,-1) so the y intercept is -1

therefore the answer is

$y=-\frac{2}{5} -1$

have a great day :)

Answer 2

Answer:

$y=-\frac{2}{5}x-1$

Step-by-step explanation:

In order to find the answer, we first need to know the slop form.

y=mx+b

In order to find the slope (m), we need to find at least 2 clear points on the graph. Looking at the graph, we can see that one point is (-5, 1) and (0, -1).

We can use either the formula $\frac{y2-y1}{x2-x1}$ or rise over run. In this scenario, looking at the graph and using rise over run will be the fastest way. Starting at point (0, -1), you have to rise 2 and run 5.

In addition, the line is going into infinite value in the second and fourth quadrant. This tells us that the slope is negative. $m=-\frac{2}{5}$.

To find the b value, all we have to do is find the y-value that is on the y-axis. (0, -1), and the answer is -1.

This, gives use the formula $y=-\frac{2}{5}x-1$

If you want to check your answer, simply plug in a random point on the line into the formula and the equation will be valid.
