Answer:
2
Step-by-step explanation:
By definition, the slope or gradient of a line describes its steepness, incline, or grade.
m = y2 - y1 / x2 - x1
Where
m — slope
If the 2 Points are Known:
Slope (m) = ΔY/ΔX
= 7-(-1) / 3-(-1)
= 8/4
= 2/1
= 2
θ = arctan (ΔY/ΔX)
= tan¯¹(8/4)
= 63.434948822922°
ΔX = 3 – (-1) = 4
ΔY = 7 – (-1) = 8
Distance (d) = √ΔX2 + ΔY2 = √80
= 8.9442719099992
Equation of the line:
y = 2x + 1
When x=0, y = 1
When y=0, x = -0.5
