Answer:
The area of triangle K is 16 times greater than the area of triangle J
Step-by-step explanation:
we know that
If Triangle K is a scaled version of Triangle J
then
Triangle K and Triangle J are similar
If two triangles are similar, then the ratio of its areas is equal to the scale factor squared
Let
z -----> the scale factor
Ak ------> the area of triangle K
Aj -----> the area of triangle J
so
we have
substitute
therefore
The area of triangle K is 16 times greater than the area of triangle J
To find the intercepts, the other number will be 0 (x-intercept: when y is 0, and vise-versa).
So:
x-intercept: <u><em>0</em></u><em> + 1 = 3x - 12 -> 3x = 13 -> </em><em>x = 13/3</em><em>, </em>so it will be<em> </em>(, 0)<em>.</em>
y-intercept:<em> y + 1 = 3*</em><u><em>0</em></u><em> - 12 -> </em><em>y = -13</em>, so it will be (0, -13).
