Answer:
C
Step-by-step explanation:
y-3=5(x-2) (rearrange this to be in slope- intercept from) (add 3 to both sides)
y = 5(x-2) + 3 (distribute parentheses)
y = x(5) - 2(5) + 3
y = 5x -10 + 3
y = 5x - 7
recall that for a line with gradient m, the gradient of the perpendicular line will be - (1/m)
hence in our case, our gradient of the original line is 5, hence the gradient of the perpendicular line is -1/5
From the choices, the only one that is consistent with this is C
i.e choice C:
5y + x = 25
5y = -x + 25
y = -(1/5) x + 5 ===> gradient of -1/5
Answer:
10
Step-by-step explanation:
because it is 10
Answer: b=4(10)^1/2
Step-by-step explanation:
Distance Formula: a^2+b^2=c^2
6^2+b^2=14^2
36+b^2=196
b^2=160
b^2=10*16
b=(10*16)^1/2
b=4(10)^1/2
