The points P, Q, R and S all lie on the same line segment, in that order, such that the ratio of PQ : QR: RS is equal to 4:2:1.
Natasha2012 [34]

Answer:

PR = 12

Step-by-step explanation:

P-----------Q-----------R----------S

ratio

4:2:1

PS = 14

add the ration = 4 + 2 + 1 = 7

14 / 7 = 2

PQ at 4 x 2 = 8

QR at 2 x 2 = 4

RS at 1 x 2 =  2

              ------------

                   14

PR = PQ + QR

PR = 8 + 4

PR = 12

Which point-slope equation represents a line that passes through (3, –2) with a slope of -4/5?
alexira [117]

Answer:

y+2=-\frac{4}{5}(x-3)

C is correct equation.

Step-by-step explanation:

We are given a point and slope of a line. Using point slope form formula to find the equation of line and match the correct option.

Formula:

y-y_1=m(x-x_1)

where,

slope (m)=-\frac{4}{5}

Point:(x_1,y_1)\rightarrow (3,-2)

Equation of line:

y-(-2)=-\frac{4}{5}(x-3)

y+2=-\frac{4}{5}(x-3)

Thus, C is correct equation of given information.
