So we will begin with the equation for any slope
it is
(y2 - y1)/(x2 - x1)
and we will put each given point in its place
(-8-(-1)) / (t -(0))
then sum up the nominator
-1 = (-7) / t -0
and to find t we have to divide -7 over -1 and add -0 which will give us 7
So the value of t is 7

What is the distance between the point (−10, −2)(−10, −2) and the point (−4, −2)(−4, −2) ?
Gnoma [55]
In this case:  x 1 = - 10,  y 1 = - 2;
x 2 = - 4 ,  y 2 = - 2
The distance between the points :
d =  \sqrt{(x 2 - x 1 ) ^{2} + ( y 2 - y 1 ) ^{2} } = \\  =\sqrt{(-4+10) ^{2} +(-2+2) ^{2} } = \\ = \sqrt{6 ^{2}+0 ^{2}  } = \sqrt{36}= 6
Answer: d = 6
