Answer:
slope=0, y-intercept=2
Step-by-step explanation:
<h2><u>Solution (1)</u> :</h2>
Given, to find A we have to :
- square m
- Add y to m²
- Subtract 7 from m² + y
From the question, the following equation can be formed :

Therefore, the formula for finding A = m² + y - 7
<h2><u>Solution (2)</u> :</h2>
The value of A we can derive from the formula is :

Value of m = 3 (given)
Which means :




Thus, the value of A = 2+y
Therefore, the value of A = <u>2+y</u>
The decimal adds a zero every time the powers of ten increase for example if u do 1 x

=100 if u do 1x

=1,000
