Slope is calculate using the following equation:
slope = (y2-y1) / (x2-x1)
since the slope is undefined, therefore, the denominator is equal to zero, which means that x2 = x1.
Based on this, the only curves with undefined slopes are the curves with equation: x = constant
Therefore, <span>equation of a line passing through a point (5,-3) with and undefined slope is x = 5</span>
The answer would be: yellow or 100 sq cm
Q: A certain type of nuts are on sale at $0.35 . Tamara buys 0.2 pounds of nuts . How much will the nuts cost
A: $1.75 simply type in “.35 divided by .2” this will give you one dollar and seventy-five cents
