Answer:
Step-by-step explanation:
- 2x + 3y = -1 is the equation of a line
Pick any values for x then find y or for y and then find x;
if you have two points you can draw a line trough those two points.
For example,
pick x= -1 then find y
- 2*(-1) + 3y = -1
2+ 3y = -1
3y = -1-2
y= -3/3
y= -1
First point has the coordinates (-1, -1)
pick y = 1 then find x
- 2x + 3*1 = -1
-2x +3 = -1
-2x = -1-3
-2x = -4
x= -4/-2
x= 2
Second point has the coordinate (2, 1)
Draw a line trough the points (-1, -1) and (2,1) to sketch the graph of -2x+3y = -1

Solution:
Given the triangle ABC as shown below:
To draw the image,
step 1: Determine the coordinates of the vertices of the triangle.
In the above graph,
![\begin{gathered} A(6,7) \\ B(9,9) \\ C(8,6) \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20A%286%2C7%29%20%5C%5C%20B%289%2C9%29%20%5C%5C%20C%288%2C6%29%20%5Cend%7Bgathered%7D)
step 2: Evaluate the new coordinates A'B'C' of the triangle after a dilation centered at the origin with a scale factor of 2.
After a dilation centered at the origin with a scale factor of 2, the iniatial coordinates of the vertices of the triangle are multiplid by 2.
Thus,
![\begin{gathered} A(6,7)\to A^{\prime}(12,14) \\ B(9,9)\to B^{\prime}(18,18) \\ C(8,6)\to C^{\prime}(16,12) \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20A%286%2C7%29%5Cto%20A%5E%7B%5Cprime%7D%2812%2C14%29%20%5C%5C%20B%289%2C9%29%5Cto%20B%5E%7B%5Cprime%7D%2818%2C18%29%20%5C%5C%20C%288%2C6%29%5Cto%20C%5E%7B%5Cprime%7D%2816%2C12%29%20%5Cend%7Bgathered%7D)
step 3: Draw the triangle A'B'C'.
The image of the triangle A'B'C' is as shown below:
