Answer:
Intercept form 
The standard form of the equation of the line
4 x + 5 y +20 =0
Step-by-step explanation:
<u><em>Explanation</em></u>
Given that x-intercept (a) = -5
and y-intercept (b) = -4
Intercept form


⇒ 
4 x + 5 y = -20
<u><em>Final answer:-</em></u>
The standard form of the equation of the line
4 x + 5 y +20 =0
<span>(a+b)(c+d)=ab+ad+bc+bd
(5k-4)(4k-5)=20k^2+-25k-16k+20=20k^2-41k+20
Hope this helps!</span>
