[tex]\bf \stackrel{slope-intercep~form}{y=mx+b}\\\\ -------------------------------\\\\ \stackrel{y}{4}=\stackrel{slope}{\cfrac{2}{5}}\stackrel{x}{(-4)}+b\implies 4-b=\cfrac{2}{5}(-4)\implies \cfrac{4-b}{-4}=\cfrac{2}{5} \\\\\\ \stackrel{y}{4}=\stackrel{slope}{-\cfrac{8}{5}}\stackrel{x}{(1)}+b\implies 4-b=-\cfrac{8}{5}(1)\implies \cfrac{4-b}{1}=-\cfrac{8}{5}[/tex]

_______________________________
4 = (2/5 × -4) + b
→ 4 = -8/5 + b
→ -b = -8/5 + (-4)
→ b = 8/5 + 4
→ b = 8 + 20 / 5
→ b = 12
Finally, b = 12
