Question

Find an equation of the line containing the given pair of points: (-5, -7) and (-3, -8). The equation of the ine in slope-intercept form is y = ?

Answer 1

slope= -8-7/-3-5
= -15/-8
=15/8
y=mx+b , m=15/8 , (-5,-7)
-7=15/8(-5)+b
-7=-75/8 +b
-56/7+75/8=b
19/8=b
so the equation is y=15/8 +19/8
