Equations in slope-intercept form follow a specific format.
Here, the slope is m and the y-interceptb. The slope of our line is 3.y=3x+b
To complete the equation of this line, we need to determine the y-intercept b. We can do that by substituting the given point (1,-1) into the equation and solving for b.
Now that we have both the slope and y-intercept, we can write the final equation.
Once again, the equation should be written in slope-intercept form.
From the exercise we know that the slope is equal to 3.y=3x+b
To complete the equation for this line, we need to determine the y-intercept b. Thus, let's substitute the given point into the equation.
