Answer:
Please check the attached figure a and figure b to check the complete solution of your question.
Step-by-step explanation:
For First Question: (Check attached figure a for complete solution)
The reflection of the point (x,y) across
the x-axis is the point (x,-y).
So, just transform the y-coordinate into its opposite - its sign is changed. But, x-coordinate remains the same.
T(-1,-1) → T'(-1, 1)
G(-3,-1) → G'(-3, 1)
B(-3,-5) → B'(-3, 5)
Translating G'T'B' 5 units right, 3 units down.
Add 5 units in x axis and subtract 3 units in y axis to get G''T''B''
T'(-1, 1) → T''(4, -2)
G'(-3, 1) → G''(2, -2)
B'(-3, 5) → B''(2, 2)
Check attached figure a for complete solution.
For 2nd Question: (Check attached figure b for complete solution)
Dilation in the coordinate plane:
Starting with ΔABC triangle with a center at the origin
and a scale factor of three.
Dilation with scale factor 3, just multiply the x and y coordinate
by 3. So, (x, y) → (3x, 3y)
.
A(-2, 2) → A'(-6, 6)
B(1, 2) → B'(3, 6)
C(1, -1) → C'(3, -3)
Check attached figure b for complete solution.
