I'm assuming the line goes through the points (1,3) and (3,9). If that's not correct, ignore this answer.
The slope of the line is 3x. The full equation of the line is y = 3x
Answer:
C) base side length = 30.6 cm, height = 27.3 cm
Solve the equation in the picture
Answer:
15) (1, 1) and (-1, 1)
16) (1, 2) and (-1, 2)
17 (1,1/2) and (-1, 1/2)
18) (1,1/4) and (-1, 1/4)
19) 16 is vertical stretch, 17 and 18 is vertical compressed
Step-by-step explanation:
for qs 15-18 since x is 1 or -1 if you sq 1 or -1 you will always get 1
so y is the "a" value in the equation y=ax²
for qs 19
y=ax²
so if a>1 -- then vertical stretch
when 0<a<1 -- then vertical compressed
