Find an equation of the line that is parallel to the graph of 2x+3y=5 and contains the point (3, −1).

uranmaximum [27]

Answer:

A) Equation of line is 3X - 2Y = 11

B) Equation of line is Y = X + 1

C) Equation of line is Y - 7 = 0

Equation of line , point (3 , -1) and slop $\frac{3}{2}$ is 3X - 2Y = 11

Step-by-step explanation:

Given equation of line as 2x + 3y = 5

slove of this line (m1) = - $\frac{2}{3}$

Now another line passes through point (3 , -1) having slop (m2)

Both lines are parallel to each other, i.e (m1) × (m2) = - 1

So slop of second line (m2 ) = $\frac{-1}{m1}$

(m2) = $\frac{-1}{(\frac{-2}{3} } )$

(m2) = $\frac{3}{2}$

Now eq of line with point (3 , -1) and slop (m2)

Y- y1 = (m2)( X - x1)

Or, Y +1 = $\frac{3}{2}$ (X - 3)

i.e 2Y + 2= 3X - 9

∴ Equation of line is 3X - 2Y = 11 Answer

B) Given points as ( 5,6) and (3 , 4)

Slop (m) = $\frac{y2 - y1}{x2 - x1}$ = $\frac{4 - 6}{3 - 5}$ = 1

So the equation of line is

Y- y1 = (m)( X - x1)

Y - 6 = (1) (X - 5)

i.e Equation of line is Y = X + 1 Answer

C) Given points as ( 0, 7) , (0 , -8)

Slop (m) with co-ordianate = $\frac{y2 - y1}{x2 - x1}$

Or, = $\frac{-8 - 7}{0 - 0}$

Hence equation of line is Y - 7 = 0 Answer

Answer:

$\displaystyle y+6=\frac{4}{5}(x+3)$

Step-by-step explanation:

Equation of the Line

The equation of a line passing through points (x1,y1) and (x2,y2) can be found as follows:

$\displaystyle y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

The graph shows two clear points (-3,-6) (2,-2). Applying the formula

\displaystyle y+6=\frac{-2+6}{2+3}(x+3)

$\boxed{\displaystyle y+6=\frac{4}{5}(x+3)}$

The ratio of female birds to male birds in a habitat is 2.4 to 1. If there are 123 female birds in the habitat, and approximatel

dusya [7]

So you will first need to divide 123 by 2.4 to get how many male birds are there. Then you need to multiply that answer by 0.4. That will be your final answer.
