: given these two points on a line, write the equation in slope-intercept form:
(5,-13) and (2,-1)
i did the coordinate approach and came out with: -1-(-13)/2-5=-4, which is the slope. to find the y=intercept, i took one of the points and did: 2=-4(-1)+b. I came out with 2=4+b. now subtracted 4 from both sides and got: 4-2=4+b-4 which simplifies to:-2=b. so my final equation would read: y=-4x+(-2). is this correct?? This question is from textbook
You can put this solution on YOUR website! YOU GOT THE SLOPE RIGHT BUT YOU SUBSTITUTED THE WRONG VALUES IN THE EQUATION
Y=mX+b
YOU SHOULD HAVE OBTAINED THE FOLLOWING FOR (2,-1)
-1=-4*2+b
-1=-8+b
b=-1+8
b=7 thus the equation foir this line is
y=-4x+7
