Question

Find the slope of the line through the given points. (-3,-18) and (1,2)

Answer 1

Answer:

5

Step-by-step explanation:

Slope (m) =

ΔY

ΔX

=

5

1

= 5

θ =

arctan( ΔY )

ΔX

= 78.69006752598°

ΔX = 1 – -3 = 4

ΔY = 2 – -18 = 20

Distance (d) = √ΔX2 + ΔY2 = √416 = 20.396078054371

Equation of the line:

y = 5x – 3

When x=0, y = -3

When y=0, x = 0.6
