Answer:

The equation of line in the form of Ax + By = C is: \mathbf{4x+y=-17}

Step-by-step explanation:

We need to find the equation of line, having slope m = -4 and passes through point (-2,-9)

First we need to find slope and y-intercept of the line.

The slope is given i.e. m = -4

Now, we need to find the y-intercept

Using the point (-2,-9) and slope m = -4, y-intercept can be found using:

y=mx+b\\-9=-4(-2)+b\\-9=8+b\\b=-9-8\\b=-17

Now, the equation of required line having slope m = -4 and y-intercept b = -17 is:

y=mx+b\\y=-4x-17

Now writing in form of Ax + By = C

y=-4x-17\\4x+y=-17

So, the equation of line in the form of Ax + By = C is: \mathbf{4x+y=-17}.

A table is 2 feet wide it is 6 times as long it is wide
yan [13]

Answer:

Length = 12 feet

Perimeter = 28 feet

Area = 24ft²

Step-by-step explanation:

You didn't ask a question so I don't know what the answer you want is so I assumed it was related to one of the answers shown above.

To calculate the length, you simply do 6*2

which is equal to 12.  

The length is 12 feet.

However, if you want to find the perimeter:

12 + 12 + 2+ 2 =  28ft

If you wanted to find the area:

12*2 = 24ft²

I hope this helps!

Write the equation of the line that passes through the points (-1, 10) and (5, 2)
sdas [7]

Answer:

y=-\frac{4}{3}x +\frac{26}{3}

Step-by-step explanation:

1) if the point A has coordinates (-1;10) and the point B - (5;2), then it is possible to write common view of the required equation of the line:

\frac{x-X_A}{X_B-X_A} =\frac{y-Y_A}{Y_B-Y_A};

2) if to substitute the coordinates of A&B into the common equation, then:

\frac{x+1}{5+1} =\frac{y-10}{2-10}; \ => \frac{x+1}{6}=\frac{y-10}{-8};

3) finally, in slope-intersection form:

3y= -4x+26; ⇔ y= -4/3 x +26/3.

P.S. the suggested way of the solution is not the only one.
