9(9 - 8x) = 2x + 3
81 - 72x = 2x + 3
+72x +72x
81 = 74x + 3
-3 -3
78 = 74x

What is the equation of the line shown written in slope-intercept form?

Snowcat [4.5K]

Answer:

The equation of the line is y = 2.

Step-by-step explanation:

When a line is horizontal, it's gradient will be 0. So you have to substitute the coordinates into the equation, y = mx + b, to find the b :

$y = mx + b$

$let \: m = 0 \\ let \: x = 5 \\ let \: y = 2$

$2 = 0(5) + b$

$b = 2$

$y = 2$

A rope is 66 feet long. It is cut into two pieces such that one piece is half the length of the other. What is the length of the

dedylja [7]

So if one bit of the length, is half the size of the other bit then we can make the following equation, for x being the length of rope:

x + 2x = 66
3x = 66
x = 22

That is the length, of the smaller one (half the big one), so 2x = 44. Hence d) is your answer.

Hope I helped!
