Answer:

(-3,-2)

Step-by-step explanation:

y = -x - 5

y = 2x + 4

plug in one of the y equations

(2x+4)= -x - 5

2x+4=-x-5

3x=-9

x= -3

plug in x to one of the y equations

y= -(-3) -5

y=3-5

y= -2

x= -3, y= -2

Answer:

Answer:

Solution given:

$(x_1,y_1)=(7,11)$

$(x_2,y_2)=(13,17)$

now

slope: $\frac{y_2-y_1}{x_2-x_1}=\frac{17-11}{13-7}=\frac{6}{6}$

Slope: 1
