Slope - Intercept Form of the Equation of a Line
1) Find the equation of a line if its slope is 2 and the value of b is -7.
[tex] \rm{y = mx + b} \\ \rm{m = 2 \: \: and \: \: b = - 7}[/tex]
- The equation of the line is
- y = 2x - 7

2) Write the equation of a line with slope of 4 and b is 3.
[tex] \rm{y = mx + b} \\ \rm{m = 4\: \: and \: \: b = 3}[/tex]
- The equation of the line is
- y = 4x + 3
