The slope-intercept form of a line is:

Where m is the slope and y is the y-intercept:

To find q (y-intercept), substitute the coordinates of the point (9, -4) in the equation of the line and solve it as an equation:
-4=3(9)+q
-4=27+q
q=-27-4=-31
The equation of the line is: y=3x-31
We are given that the shorter piece is x
From your description, the longer piece is 2x + 2
The total length is
x + 2x + 2 = 14
ie
3x + 2 = 14
3x = 12
x = 4
So the length of the shorter piece is 4 ft
Therefore the length of the longer piece must be
(14 - 4) ft = 10 ft
Answer:
6 = 600
Step-by-step explanation:
in a decimal number the digits to the left of the decimal point represent a whole number
We have x, so we need to find y. We just need to plug in 4 and solve the equation.
2•4+3=y
8+3=y
11=y
The coordinate would be
(4,11)
