It these triangles are similar, then the sides of the triangles are in proportion:
<em>cross multiply</em>
<em>use distributive property</em>
<em>subtract 10y from both sides</em>
<em>divide both sides by 5</em>
<em>cross multiply</em>
<em>divide both sides by 8</em>
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

Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the
10
. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
