The equation for line 1 is…

y= -2x-5

Step-by-step explanation:

use y=mx+b

m=slope

b=y-intercept

from the graph you can see that the y-intercept is -5, so your b would be -5.

for slope, you can either use "rise over run" or find the slope using two points.

the slope is -2, so your m would be -2.

y=-2x-5

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

the correct answer is x/3+10≥32

hope this !
