Answer: -7.5
Step-by-step explanation:
area = 1/2bh.
area = 1/2(x+6)(5)
area = x/2 + 15
area = x/2 = -15
area = x = -7.5
area = -7.5
Linear functions always go up by the same value. You can subtract 2 y values and divide it by the corresponding x values (subtracted the same way) and you will get the same number. Here is an example from ur chart. 3). (9-7)/(3-2) = 2. Now try it for another two values. You get 2. That means it is linear. The equation for it would be y=2x+3
Now do the next one good luck!
Reflecting through x=0 maps x to -x so
g(x) =f(-x) = -2x
Answer: y = -2x
Can't see the choices, look for a downward slope of two units down for every unit to the right, through the origin.
