Write an equation of the line through (6,-5) having slope 0. Give the answer in standard form.
allsm [11]

0x + 1y = -5 is the standard form of equation

<em><u>Solution:</u></em>

Given that we have to write the equation of line passing thorugh (6, -5) and has slope 0

<em><u>The equation of line in slope intercept form is given as:</u></em>

y = mx + c ---------- eqn 1

Where, "m" is the slope of line and "c" is the y - intercept

Given that, m = 0

Given point is (6, -5)

<em><u>To find the y - intercept:</u></em>

<em><u>Substitute (x, y) = (6, -5) and m = 0 in eqn 1</u></em>

-5 = 0(6) + c

c = -5

<em><u>Substitute c = -5 and m = 0 in eqn 1</u></em>

y = 0x + (-5)

y = -5

<em><u>The standard form of equation is given as:</u></em>

The standard form of an equation is Ax + By = C

In this kind of equation, x and y are variables and A, B, and C are integers

y = -5

0x + 1y = -5 is the standard form of equation

I WILL GIVE YOU 40 POINTS AND THE HIGHEST ANSWER. YOU HAVE TO DO WHAT THE STEPS SAYS IN ORDER TO GET EVERYTHING
Marat540 [252]
This is a 30-60-90 triangle, in which the side opposite of the 90 degrees is the longest side (2), the side opposite of the 60 degrees is the √3 (2√3 in this case), and the last side (opposite of the 30 degrees) is the (1)

2√3/√3 = 2

So the side opposite  of the 30° = 2

a) the width is 2 miles

The length of the side walk is 2(a)
a = 2

2(2) = 4

b) The length of the sidewalk is 4 miles

hope this helps
