slope of x-intercept of 20x+15y=120
To find the slope of the x-intercept, we need to set y=0 and solve for x.
20x + 15(0) = 120
20x = 120
x = 120/20
x = 6
Therefore, the x-intercept is 6. Since the x-intercept lies on the x-axis, its slope is 0.
To find the slope of the x-intercept of the equation 20x + 15y = 120, we need to find the value of y when x = 0 at the x-intercept.
Step 1: Substitute x = 0 into the equation:
20(0) + 15y = 120.
Simplifying the equation:
15y = 120.
Step 2: Solve for y:
y = 120 / 15.
Simplifying further:
y = 8.
So, the x-intercept is when y = 8.
Step 3: Since the x-intercept is when y = 8, the slope of the x-intercept is undefined.
