1. What is the slope of the line passing through (-2,3) and (4, -5)?
2. Which of the following is the equation of a line that has a slope of zero and passes through the point (4,6)?

Step-by-step explanation:

hello :

1) Hello :

let  A(-2,3)    B(4,-5)

the slope is :   (YB - YA)/(XB -XA)

(-5-3)/(4+2)  =  -8/6 =-4/3

2) Use the point-slope formula.

y - y_1 = m(x - x_1)    you have :

m=0      x_1=4        y_1=6

an equation for this line is : y-6 =0(x-4)

so : y=6
