A line contains the points (-7,15) and (10,27) what is the slope of the line as a simplified fraction?

Gwar [14]

Answer:

The slope of line for given points is $\frac{12}{17}$

Step-by-step explanation:

Given points of line as :

A = ( - 7 , 15 ) i, e $x_1$ = - 7 , $x_1$ = 15

B = ( 10 , 27 ) i.e $x_2$ = 10 , $y_2$ = 27

Let The slope of line be m

So , The slope with two points is given as equation

m = $\frac{y_2 - y_1}{x_2 - x_1}$

Or, m = $\frac{27 - 15}{10 + 7}$

Or, m = $\frac{12}{17}$

Hence The slope of line for given points is $\frac{12}{17}$ . Answer

Answer:

Step-by-step explanation:

Equation y = 3x + 210

if y = 10x

10x = 3x + 210

or, 10x - 3x = 3x + 210 - 3x

or, 7x = 210

or, x = 210 ÷ 7

or, x = 30
