The standard form:

The slope-intercept form:

m - slope
b - y-intercept
We have m = 3 and b = -5.
Substitute:
subtract 3x from both sides
change the signs

Answer:
1. yes, both triangles sides are congruent
2. yes, they have congruent sides and they have a congruent angle
3. yes, congruent sides and angle
4. yes, 2 congruent angles
5. no, only one congruent angle not enough proof
6. yes, 2 congruent angles
7. no, only one congruent angle not enough proof
8. no, only one congruent side
Hence the correct answer is C) -23
Further explanation:
We have to put the values of m and n into both expression first separately and then multiply the answers.
Given expressions are:

The values are:

Putting the values in expression 1:

Putting the values of m and n in second expression

Multiplying both expressions:

Hence the correct answer is C) -23
