Aline contains the point (4, 5) and is perpendicular to a line with a slope of . write an equation of the line satisfying the given conditions. write the answer in slope-intercept form.

See example below.

Step-by-step explanation:

This question does not state the slope. But here is an example with the same point (4,5). Perpendicular lines have negative reciprocal slopes. If the slope of one line is -8, its perpendicular line will have the slope of 1/8.

Substitute m = 1/8 and (4, 5) into the point slope form of a line.

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
