(0,-1)(2,0)
slope = (0 - (-1) / (2 - 0) = 1/2
y = mx + b
-1 = 1/2(0) + b
-1 = b
ur equation is : y = 1/2x - 1
ur x intercept can be found by subbing in 0 for y and solving for x
0 = 1/2x - 1
-1/2x = -1
x = 2.....or (2,0) <== ur x intercept
Answer:
-24
Step-by-step explanation:
To find the area you do base a +base b times height and divide by 2 and you have the area
Answer:
(4,4).
Step-by-step explanation:
First find the axis of symmetry:
y = 3x^2 - 12x + 4
y = 3(x^2 - 4x) + 4
y = 3 [(x - 2)^2 - 4] + 4
y = 3(x - 2)^2 - 8
So the axis of symmetry is x = 2.
The y intercept of the function y is where x= 0 and y = 4 - that is (0,4).
The mirror point for the y intercept is the reflection of (0,4) in the line x = 2.
That is (2*2, 4) = (4,4).
