Answer: y = -x + 7
Step-by-step explanation:
The slope is , so we know the equation is of the form
.
Substituting in the coordinates (1,6) to find b,
Thus, the equation is y = -x + 7
In a stairway, the slope of the handrail is the ratio of the riser to the tread. If the tread is 12 inches long and the riser is
8 inches long, find the slope.
