Answer:
<em>Question 7. Option B,</em>
<em>Question 8. Option C</em>
Step-by-step explanation:
<em>Question 7.</em>
Let us create a proportionality, and solve for the value of s, through cross multiplication;
<em>Question 8.</em>
We can solve this problem in a similar manner, through setting a proportionality and solving for the length of the shadow of the tree, which we can pose as x;
Answer:
4x - 3y -18 = 0 or y = 4x/3 - 6
Step-by-step explanation:
We will have to find the slope of the line first
The formula for slope:
The standard form of equation of a line is:
y = mx + b
We know m,
So the equation will be:
We have to find the value of b, for that we will put any one of the point in the equation
So, putting (6,2)
2 = 4/3 * 6 + b
2 = 8 +b
b = -6
Putting the value of m and b in the standard form of equation of line,
..
