Answer:
y = 2x - 13
Step-by-step explanation:
Equation of a line is y = mx + c, m is the gradient and c is the intercept
The line passes through points 4 and -5, x is 4 and y is -5
-5 = 4m + c
When two lines are perpendicular, the products of their gradients are equal to -1, m1 * m2 = -1
x + 2y = 5
2y = -x + 5
y = (-1/2 * x) + 5
therefore m = -1/2
m1 * m2 = -1
m * -1/2 = -1
-m = -2 , therefore m = 2
-5 = 4 * 2 + c
c = -5 - 8, which is -13
Therefore the equation for the line is
y = 2x - 13
NO. They are not.
We can prove this by turning those numbers into fractions:
16 / 14 = 1.1428 ; 64 / 60 = 1.0667
Or simply:
64 / 16 = 4
60 / 14 = 4.29
To get the equivalent of 16 to 14; we must multiply both numbers by 4.
16 * 4 = 64
14 * 4 = 56
The equivalent of 16 to 14 is 64 to 56.
The answer would be 54 since m=-2
Step one: 4(-2+5)+42
Step two: (-8+20)+42=54
