Answer:
Step-by-step explanation:
y = 2/5x + p
We now that passes through (–2, 4)
2/5 × (-2) + p = 4
⇔ -4/5 + p = 4
⇔ p = 4 + 4/5
⇔ p = 20/5 + 4/5
⇔ p = 24/5
⇒ y = 2/5x + 24/5
Equation of a line is given by y - y1 = m(x - x1); where m is the slope.
y - 4 = 2/5 (x - (-2))
y - 4 = 2/5 (x + 2)
Hope this helps! :)

I use an app called Socratic also it works very well!!
First number is a and second one is 2a+4
a(2a+4)=48
a(a+2)=24
a^2+2a-24=0
(a+6)(a-4)=0
the question says a is negative so a=-6 b=-8
