Answer:
The slope of the line m = 1
The equation of the straight line x -y -7=0
Step-by-step explanation:
<u><em>Explanation:-</em></u>
In the given graph
The points are ( 7,0) and ( 0, -7)
The slope of the line

The equation of the straight line passing through the point (7,0) and slope m=1
y - y₁ = m (x - x₁)
y - 0 = 1( x-7)
y = x -7
x - y -7=0
<u><em>Final answer:-</em></u>
The slope of the line m = 1
The equation of the straight line x -y -7=0
