The y/x is proportional per point (x,y) since this is a direct variation.
That is ,
.
Cross multiply:

Simplify:

Divide both sides by -3


Based on the data given on the number pattern, 4 + 5 = 180
<h3>Number pattern</h3>
7 + 9 = 254016
3 + 7 = 7779240
5 + 8 = 2496000
7 + 9 = (7 × 9)^|7-9| × (7 + 9) × |7 - 9)
= 69² × 16 × 2
= 4761 × 16 × 2
= 254,016
3 + 7 = (3×7)^|3-7| × (3+7) × |3-7|
= 21⁴ × 10 × 4
= 194,481 × 10 × 4
= 7,779,240
So,
4 + 5 = (4×5)^|4-5| × (4+5) × |4-5|
= 20¹ × 9 × 1
4 + 5 = 180
