We are given that the x-intercept of line L is twice that of the line 3x + 4y = 24, and the y-intercept of line L is half of that of the same line. We need to find the slope of line L.
Step 1: Find the intercepts of the given line (3x + 4y = 24)
To find the x-intercept, set y = 0 in the equation 3x + 4y = 24:
3x + 4(0) = 24
3x = 24
x = 8
So, the x-intercept of the given line is 8.
To find the y-intercept, set x = 0 in the equation 3x + 4y = 24:
3(0) + 4y = 24
4y = 24
y = 6
So, the y-intercept of the given line is 6.
Step 2: Use the conditions for line L
The x-intercept of line L is double that of the given line, so the x-intercept of line L is 2 * 8 = 16.
The y-intercept of line L is half that of the given line, so the y-intercept of line L is (1/2) * 6 = 3.
Step 3: Write the equation of line L
The equation of a line in intercept form is:
x/x-intercept + y/y-intercept = 1
For line L, the intercepts are 16 and 3. So, the equation of line L is:
x/16 + y/3 = 1
Step 4: Rearrange to find the slope
Rearranging the equation of line L to the slope-intercept form (y = mx + c):
y/3 = 1 - x/16
y = 3(1 - x/16)
y = 3 - 3x/16
So, the slope of the line is the coefficient of x, which is -3/16.
Final Answer:
The slope of line L is -3/16.
