can someone help with any of these please?

1. A line passes through the points (-1, -6) and (-4, 3) what is the equation in slope intercept form?

2. The slope of the line that contains the points (-5, 13) and (5, -7) is -2, which of the following equations represents this line?

2a) y= -2x - 17
2b) y= -2x - 3
2c) y= -2x + 3
2d) y= -2x + 23

3. What is the equation in slope-intercept form, of the line that contains the points (3, -4) and (5, -6)?

3a) y= -x - 1
3b) y= -x + 1
3c) y= x - 1
3d) y= x + 1

Respuesta :

1. X1 Y1. X2, Y2

(-1,-6). ( -4,3)

Formula for slope which is m

Y2 -Y1 divide by X2-X1

3- -6/ -4 - -1= 9/-3= -3

So M = -3

Y=mx+b

-6= -3 (-1) +b

-6= 3+b

-3=-3

-9=b

Answer Y= -3x-9

2. X, Y

(-5,13)

Y=mx+b

13= 10+b

-10=-10

3=b

Answer C y= mx+b

y=-2x+3

3. (X1,Y1). (X2,Y2)

(3,-4). (5,-6)

Formula for m which is slope y2-y1 / x2-X1

-6- -4 / 5-3 = -2/2= -1 so m = -1

X, Y

(3,-4)

Y=mx+b

-4= -1(3)+b

-4= -3+b

+3=+3

-1. = b

Y= m x+b

-4= (-1) 3 +b

-4= -3. + b

+3= +3

-1. = b

Answer A y= -1x-1
