Question

What is the slope of a line with coordinates (5,3) and (1,2)?

A (1,4)
B 4
C (1,2)

Answer 1

1/4

Explanation:

m=(y2-y1)/(x2-x1)

m=(2-3)/(1-5)

m=-1/-4

m=1/4

Answer 2

Slope (m) =

ΔY

ΔX

=

1

4

= 0.25

θ =

arctan( ΔY ) + 180°

ΔX

= 194.03624346793°

ΔX = 1 – 5 = -4

ΔY = 2 – 3 = -1

Distance (d) = √ΔX2 + ΔY2 = √17 = 4.1231056256177

Equation of the line:

y = 0.25x + 1.75

or

y =

1 x

4

+ 7

4

When x=0, y = 1.75

When y=0, x = -7
