Write the equation of a line with an undefined slope and point (1, 7).

Sonja [21]

Answer:

The equation of straight line is x = 1

Step-by-step explanation:

<u>Step </u>:-

The equation of straight line having slope 'm' and passing through the point

$(x_{1} ,y_{1} )$ is $y-y_{1} = m (x-x_{1} )$

Slope of horizontal line(that is x-axis) is m = 0

slope of vertical line (that is y-axis) is m is not defined

The equation of straight line having slope is not defined and passing through the point (1,7).

$y-7 = \frac{1}{0} (x-1)$

cross multiplication we will get equation

$(y-7)(0)=1(x-1)$

x-1 = 0

The equation of straight line is x = 1

Find the length of the missing side please help

kozerog [31]

Step-by-step explanation:

7. Since they are similar triangles we have:

$\frac{10}{8} = \frac{x}{12} \\ \\ x = 15$

So DF is 15

8. They are also similar. So:

$\frac{14}{7} = \frac{x}{5} \\ x = 10$

So PR is 10
