The line y = -1 is a horizontal line passing through the point (0, -1).
Draw it.
Find the point (0, -1) and draw a line through it.
It is a line parallel to the x-axis.
The system of equations that Sam can use is given by:
A 13b + 4t =327.50, 6b + 2t = 142.96
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
- Variable b: Cost of a bush.
- Variable t: Cost of a tree.
The first order was for 13 bushes and 4 trees, and totaled $327.50, hence:
13b + 4t = 327.50.
The second order was for 6 bushes and 2 trees, and totaled $142.96, hence:
6b + 2t = 142.96.
Which means that option A is correct.

Answer:
3
Step-by-step explanation:
The scale factor of the dilation of segment HG is 
.
Now, PG' = 0.5 units
As per the rule of scale factor:
, where SF represents the scale factor.
Solving for PG, we get:
Therefore, the length of the segment PG is 3 units.
The slope-intercept is the first option, y=-3x-6
