Find the distance between the points 6,7 and -3,7

I think it is 8! Sorry if it's wrong!

use the distance formula:

\sqrt{(x2 -x1)^{2} + (y2-y1)^{2} }

(x2−x1)

2

+(y2−y1)

2

so, with your two points, x2=6, x1=-3, y2=7, and y1=7

so then just plug in the values

\sqrt{(6--3)^{2} + (7-7)^{2} }

(6−−3)

2

+(7−7)

2

because you have 6 minus a negative number, it turns into 6+3, like shown

\sqrt{(6+3)^{2} + (7-7)^{2} }

(6+3)

2

+(7−7)

2

so then add and subtract the parenthesis

\sqrt{(9)^{2} + (0)^{2} }

(9)

2

+(0)

2

so then because 0 squared is just zero, you simply have the square root of 9 squared

i believe that the answer is

b. y-1=-2(x-4)

hope this !
