Which graph represents the sequence: 80, -40, 20

1 answer:

8 0

80/-40=-40/20=-2,
the sequence: 80, -40, 20 is a geometric sequence
its general formula is Vn+1 = q Vn, where q= -2,
if we put Vn+1 = f(x)
 Vn = x

so we have f(x)= -2x so the graph that represents the sequence is graph of linear equation

Write the equation of a line passing through the points (2, -4) and (2, -9). Write the equation in slope-intercept form.

Norma-Jean [14]

1. find our slope: y2 - y1/ x2- x 1

-9 + 4= -5
2 - 2 = 0

m = 0

2. now we need to use our point-slope form to find our y intercept

point-slope form: y - y1 = m(x - x1)

y + 4 = 0(x - 2)

distribute:
y + 4 = 0x

3. get y by itself

y + 4 - 4 = y
0x - 4 = 0x - 4

4. write in slope-intercept form:

y = 0x - 4
OR
y = -4
