(-2,-4) ;m =3 in point slope form please

zalisa [80]

$\huge\boxed{y+4=3(x+2)}$

Point-slope form is $y-y_1=m(x-x_1)$ , where $m$ is the slope and $(x_1,y_1)$ is a point on the line.

Substitute in the values. $y-(-4)=3(x-(-2))$

Simplify the negative subtraction to addition. $\boxed{y+4=3(x+2)}$

A paddleboat can move at a speed of 4 km/h in still water. The boat is paddled 12 km downstream in a river in the same time it

Bas_tet [7]

Answer:

Speed of the river = $\frac{4}{3}$ km per hour

Step-by-step explanation:

Speed of the boat in still water = 4 km per hour

Let the speed of the river = v km per hour

Speed of the boat upstream = (4 - v) km per hour

Time taken to cover 6 km = $\frac{\text{Distance}}{\text{Speed}}$

= $\frac{6}{4-v}$ hours

Speed of the boat downstream = (4 + v) km per hour

Time taken to cover 12 km = $\frac{12}{4+v}$ hours

Since, time taken by the boat in both the cases is same,

$\frac{6}{4-v}= \frac{12}{4+v}$

6(4 + v) = 12(4 - v)

24 + 6v = 48 - 12v

12v + 6v = 48 - 24

18v = 24

v = $\frac{24}{18}$

v = $\frac{4}{3}$ km per hour
