Question

How do I solve other problems like this?
y=mx+b

Answer 1

Answer: B

Explanation:

m is the value of the slope between the two points on the graph

If the two coordinates is (x1,y1) and (x2,y2), the slope is (y1-y2) / (x1-x2)

So the slope for this question is (1-(-3)) / (-2-0) = -2 so the answer is B

Answer 2

y = -2x - 3

Explanation:

in the equation y = mx + b,

m = slope b = y-intercept

The y-intercept is provided in the point, (0, -3), because that is where it crosses the y. You're y-intercept is -3

Now you need to find slope. You need to find the difference between these two points to find slope.

`-2+0 = -2`

`1-3=-2`

so your slope is going down by 2 and to the left by 2.

Hope this helps! Might be wrong. Try with another example and tell me if it works. <3
