An equation in slope-intercept form follows a specific format.
y= mx+b
For an equation in this form, m is the slope and b is the y-intercept. Let's use the given points to calculate m. We will start by substituting the points into the Slope Formula.
A slope of -1 means that for every 1 horizontal step in the positive direction, we take 1 vertical step in the negative direction. Now that we know the slope, we can write a partial version of the equation.
y= -1 x+b
To complete the equation, we also need to determine the y-intercept, b. Since we know that the given points will satisfy the equation, we can substitute one of them into the equation and solve for b. Let's use ( 4, -2).
