Step-by-step explanation:

Given points are:

$(-1,\:3)=(x_1,\: y_1) \:\&\:(1, \:7)=(x_2,\:y_2)$

Equation of line in two point form is given as:

$\frac{y-y_1 }{y_1 - y_2} = \frac{x-x_1 }{x_1 - x_2} \\ \\ \therefore \: \frac{y - 3}{3 - 7} = \frac{x - ( - 1)}{ - 1 - 1} \\ \\ \therefore \: \frac{y - 3}{ - 4} = \frac{x + 1}{ - 2} \\ \\ \therefore \: \frac{y - 3}{ 2} = \frac{x + 1}{ 1} \\ \\ \huge \purple{ \boxed{\therefore \:y - 3 = 2(x + 1)}} \\ this \: is \: the \: equation \: of \: line \: in \: \\ point - slope \: form.\\simplifying \: it \: further \: we \: find: \\ y - 3 = 2x + 2 \\ \\ \therefore \:y = 2x + 2 + 3 \\ \\ \huge \red{ \boxed{\therefore \:y = 2x + 5}} \\ this \: is \: the \: equation \: of \: line \: in \: \\ slope - intercept \: form.$

Describe the values of c for which the equation has no solution. |x+8|=c

satela [25.4K]

An absolute value cannot equal a negative number. So c, if it was a negative number, would have no solution.

Ram donated 2/3 of his monthly income to an NGO, working for the education of the girls, spent 1/5th of his salary on purchasing

OleMash [197]

Answer:

Step-by-step explanation:

Let Ram's salary = ₹ x

Money donated to NGO = (2/3) of x

Money spent on food items = (1/5) of x

Other expenses = (1/5) of x

Balance amount = ₹ 9000

$x - (\dfrac{2}{3}x+\dfrac{1}{5}x+\dfrac{1}{15}x) = 9000\\\\\\x - (\dfrac{2*5}{3*5}x+\dfrac{1*3}{5*3}x+\dfrac{1}{15}x)=9000\\\\\\x-\dfrac{10x+3x+1x}{15}=9000\\\\\\x-\dfrac{14}{15}x=9000\\\\\\\dfrac{15}{15}x-\dfrac{14}{15}x=9000\\\\\\\dfrac{1}{15}x=9000$

x = 9000 * 15

x = ₹ 135000
