<u>Answer:</u>
<u>Step-by-step explanation:</u>
<u>Let's find 'a' using Pythagoras theorem.</u>
- => 4² = 2² + a²
- => 16 = 4 + a²
- => 12 = a²
- => a = √12
- => a = √2 x 2 x 3
- => a = 2√3
- => a = 2 x √3
- => a = 2 x 1.732
- => a = 3.464 = 3.5 (Estimated)

Answer:
y=-49
Step-by-step explanation:
Answer:
y = x - 4
Step-by-step explanation:
<u>Use point slope form: (y - y1) = m(x - x1)</u>
m = 1
<u>Step 1: Plug in</u>
(y - (-3)) = 1(x - 1)
y + 3 - 3 = x - 1 - 3
y = x - 4
Answer: y = x - 4
