Find the equation of the line that goes through the points (4, –1) and (2, –5).

poizon [28]

Answer:

y= 2x -9

Step-by-step explanation:

<u>Slope-intercept </u><u>form</u>

y= mx +c, where m is the slope and c is the y-intercept.

$\boxed{slope = \frac{ y_{1} - y_2}{x_1 - x_{2}} }$

Slope

$= \frac{ - 1 - ( - 5)}{4 - 2}$

$= \frac{ - 1 + 5}{2}$

$= \frac{4}{2}$

= 2

Substitute m= 2 into the equation:

y= 2x +c

To find the value of c, substitute a pair of coordinates.

When x= 4, y= -1,

-1= 2(4) +c

-1= 8 +c

c= -1 -8

c= -9

Thus, the equation of the line is y= 2x -9.

Answer:

For $\frac{6}{25} = \frac{d}{30}$ , d = 7.2

Step-by-step explanation:

Here, the given expression is $\frac{6}{25} = \frac{d}{30}$

To find the value of the variable d :

$\frac{6}{25} = \frac{d}{30} \implies d = \frac{6}{25} \times 30$

or, $d = \frac{180}{25} = \frac{36}{5 } = 7.2$

Hence, for $\frac{6}{25} = \frac{d}{30}$ , d = 7.2
