Question

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)?

Answer 1

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
