Find the slope-intercept equation of the line that has the given characteristics.

Slope – 3 and y- intercept – 4

Solution

The easily ways to write an equation for the line is to use the slope- intercept equation, where m is the slope and b is the y-intercept.

The slope-intercept equation is y = mx + b .

To write the equation you simply substitute -3 for m.

Y = -3x + b.

Then substitute – 4 for b.

Y = -3x – 4

Y = -3x – 4 is the slope-intercept equation for the given slope and y-intercept.
