Find the y intercept​
erica [24]

Step-by-step explanation:

Slope of line ST = Slope of line PQ = -3.

y = -3x + c

When x = 3, y = -1

=> (-1) = -3(3) + c, c = 8

Therefore the equation of line ST is y = -3x + 8 and the y-intercept is 8.

Help please??????????????
11111nata11111 [884]

Answer:

9.8

Step-by-step explanation:

a geometric sequence means we multiply the previous element by a certain factor to get the next element.

so, all we need to do is determine the factor used to go from one element in the list to the next.

a1 = 9

a2 = 88.2

a3 = 864.36

a4 = 8470.728

the simplest case is usually the case from a1 to a2.

a2 = a1×f

88.2 = 9×f

f = 88.2/9 = 9.8

we are finished here.

but we can control our result and verify with the other given elements.

88.2 × 9.8 = 864.36

and that is a3. fits.

864.36 × 9.8 = 8470.728

and that is a4.

so, all fits, we are correct.
