Y = mx + b is <span> the "slope-intercept" form of the equation of a line ;
We have y = -x + 6 ;
Then, m = - 1 ;
</span><span>The "point-slope" form of the equation of a straight line is:
</span><span>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;
________________________________________
</span><span>y – 3 = (x – 1) ; the equation becames
</span>
y = x + 2 ;
The right answer is the third choice;
Answer:
yes
Step-by-step explanation:
Answer: d (A,B) = 9
Step-by-step explanation: d(A,B) = √(xB - xA)^2 + (yB - yA)^2
d(A,B) = √(8-(-1))^2 + (-3 - (-3))^2
d(A,B) = √81 + 0
d(A,B) = 9
