Question

4. What is the slope of the equation? y = -x + 3​

Answer 1

y = mx + b is the "slope-intercept" form of the equation of a line ;

We have y = -x + 6 ;

Then, m = - 1 ;

The "point-slope" form of the equation of a straight line is:

y - y1 = m(x - x1) ;

But, x1 = - 3 and y1 = 8 ;

We have y - 8 = (-1)( x + 3 );

Finally, y - 8 = -( x + 3 );

The right answer is the fourth choice;

________________________________________

y – 3 = (x – 1) ; the equation becames

y = x + 2 ;

The right answer is the third choice;

Explanation:

Answer 2

The slope of the equation is -1
