Question

Find the slope of line whose end points are (2,-5) and (4,-7)​

Answer 1

m = -1

Explanation:

`\mathrm{Slope}=(y_2-y_1)/(x_2-x_1)\\\\\left(x_1,\:y_1\right)=\left(2,\:-5\right),\\\:\left(x_2,\:y_2\right)=\left(4,\:-7\right)\\\\m=(-7-\left(-5\right))/(4-2)\\\\m = (-7+5)/(4-2)\\ \\m = (-2)/(2)\\ \\Simplify\\\\m =-1`
