Equation is 2x + y = -4
Step-by-step explanation:
- Step 1: Use the point slope form to get the equation. The point is (x1, y1) = (-4, 4) and slope, m = -2
Point slope Form ⇒ y - y1 = m(x - x1)
⇒ y - 4 = -2(x - -4)
⇒ y - 4 = -2(x + 4)
⇒ y - 4 = -2x - 8
⇒ 2x + y = -4 is the equation
The shorter piece is 3/10 of the 1.5m long piece of wood.
1.5/10=0.15
0.15*3=0.45
The shorter piece is 0.45m or 45cm long.
Hope this helps :)
