Hello, please consider the following.
a) You need to replace x by -1.

b) You need to replace x by 2t and simplify.

c) You need to replace x by t-2 and develop, and simplify.

Thank you.
Slope =change of y over change of x
(2, −5) and (4, 1)
M= 1-(-5)/4-2
M=6/2
M=3
So the slope is 3.
If you need the equation
Y=mx+b
(4, 1)
1= 3(4)+b
1=12+b
1-12=b
-11=b
So equation
Y=3x-11
Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation as 6.5 ✕ 10^8.
