Question

2- a line passes through (1, –5) and (–3, 7).write an equation for the line in point-slope form. rewrite the equation in slope-intercept form

Answer 1

answer is y=3x-8
(7-(-5))divide(1-(-3))=3 3 mean slope

Answer 2

Hello : let A(1,-5) B(-3,7)
the slope is : (YB - YA)/(XB -XA)
(7+5)/(-3-1) = -3
an equation is : y=ax+b a is a slope

y = -3x +b

the line through point (1,-5) : -5 = (-3)(1)+b
b =-2
the equation is : y =-3x-2

or : 3x+y= -2
