Slope Intercept Form
y = mx + c

Slope Intercept Form is also called as gradient, y-intercept form. Slope Intercept Form is used to generate the Equation of a straight line with a slope m and y - intercept c of the line.

Calculate the equation of the line with slope of 4 and y-intercept 3.
slope m = 4.
slope c = 3.
Substitute in the formula as :
y = mx + c
y = (4)x + (3)
y = 4x + 3
Equation = 4x + 3 -y

Equation of the Line = 4x -y + 3
