Question

Write an equation for a line in slope-intercept form that passes through the points (3, 4) and (1, -2).

Answer 1

Equation is \[\large y=3x-5\]

See attached image for work

Answer 2

-2-4/1-3
-6/-2
3
y=mx+b , m=3 , (3,4)
4=3(3)+b
4=9+b
-9+4=b
-5=b

y=3x-5

Answer 3

slope =m= y2-y1/x2-x1 = -2-4/1-3 = -6/-2=3
equation
y-4=3(x-3)
y=3x-5
