Answer:
graph on top right
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange 10x + 5y = 20 into this form
Subtract 10x from both sides
5y = - 10x + 20 ( divide all terms by 5 )
y = - 2x + 4 ← in slope- intercept form
with slope m = - 2 and y- intercept = 4
Since slope < 0 then line slopes downwards from left to right
There are 3 graphs sloping downwards from left to right
Consider the y- intercept value = + 4
Top left graph has a y- intercept = - 4
Top right graph has a y- intercept of + 4
Bottom left graph has a y- intercept of + 2
Hence the required graph is the top right
