1.find the x-intercept and the y-intercept without graphing. write the coordinates of each intercept. 5y = 2x – 1 x-intercept (x, y) = y-intercept (x, y) =

see explanation

Step-by-step explanation:

The x- intercept is where the line crosses the x- axis. Let y = 0 in the equation and solve for x

5(0) = 2x - 1, that is

0 = 2x - 1 ( add 1 to both sides )

1 = 2x ( divide both sides by 2 )

The x- intercept is ( , 0 )

The y- intercept is where the line crosses the y- axis. Let x = 0 in the equation and solve for y

5y = 2(0) - 1

5y = - 1 ( divide both sides by 5 )

y = -

The y- intercept is (0, - )

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
