Answer:
Step-by-step explanation:
we know that
the formula to calculate the distance between two points is equal to
we have
substitute the values
-4x + 9y = 9...............(1)
x - 3y = -6 Multiply through by 3:-
3x - 9y = -18..............(2)
adding equations (1) and (3):-
-x = -9
x = 9
Substitute for x in equation (1)
-4(9) + 9y = 9
-36 + 9y = 9
9y = 45
y = 5
Answer is x = 9 and y = 5
Given:
The function is
The secant line passing through (-4,f(-4)) and (2,f(2)).
To find:
The equation of the secant line.
Solution:
We have,
At x=-4,
At x=2,
The secant line passes through the points (-4,-66) and (2,6). So, the equation of the secant line is
On further simplification, we get
Therefor, the equation of the secant line is .
