PLEASE SOMEONE!!HELP!! I need the answer right now
1 answer:
Answer:
m = -1, b = 5.
Step-by-step explanation:
We can find the slope, <em>m</em>, by plugging in our coordinates into the slope formula: . That gives us the slope. Now we can fill that in the slope intercept formula:
. We know one of the coordinates and the slope, which allows to find the y-intercept. We know that for every 1 unit down on the line, we move 1 unit right, and vice versa. Meaning we can just count down (or up in this case), so, (-2, 7), (-1, 6), (0, 5). Therefore, our y intercept is 5.

Given:
The algebra tiles of an equation.
To find:
The equation represented by the given model.
Solution:
On the left side of the model we have 4 tiles of (-x) and 3 tiles of (-1). So,
On the right side of the model we have 8 tiles of (-1). So,
Now, equate the LHS and RHS to get the equation.
Therefore, the equation for the given model is .
