Line slope calculator 5x+y=45


Enter coordinates of two different points:

Straight line given by points A[7; 10] and B[8; 5]

Calculation:

Slope-intercept form of line: y = -5x+45

Canonical form of the line equation: 5x+y-45 = 0

Parametric form of the line equation:
x = t+7
y = -5t+10      ; t ∈ R

Slope: m = -5

Slope angle of line: φ = -78°41'24″ = -1.3734 rad

X intercept: x0 = 9

Y intercept: y0 = q = 45

Distance line from the origin: d0 = 8.8252
