O y=-2x + 6
O y=-*x+2
O y=2x + 2
Answer:
None of the answers is correct based on the points given
Step-by-step explanation:
1. Use the slope formula (see image)
Based on the points given the slope is actually undefined.
Answer:
y = 4
Step-by-step explanation:
Calculate the slope m using the slope formula
m =
with (x₁, y₁ ) = (1,4) and (x₂, y₂ ) = (3, 4)
m = = = 0
This indicates the line is horizontal and parallel to the x- axis with equation
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (1, 4) and (3, 4) with y- coordinates of 4, thus
y = 4 ← equation of line
Answer:
A line is a 1 dimensional thing used to create 2 dimensional shapes.
Answer:
Step-by-step explanation:
an equation of this tangent is : y = f'(4)(x-a)+f(4)
a = f'(4)
f(x) = - x²
a=4
f'(x) = -2x
f'(4) = -2(4) = -8
f(4) = -(4)² = -16
so : y = - 8 (x-4)-16
y = - 8x +16
