What you must do for this problem is to re-imagine the equation in "vertex form"
Vertex form:
where "h" shifts the graph to the right if "h" is positive" and to the left if "h" is negative. K shifts the graph up and down.
a=1
h=1
k=0
So, your final answer should be:
The slope is the change in Y over the change in X.
Slope = (0 - 1) / 4-2)
= -1/2
The slope is -1/2
The equation and steps are...
First, find the slope of the original equation. In this case, the slope is -8. You know that perpendicular lines have slopes that are negative reciprocals, so the negative reciprocal of -8 is 1/8.
Now, use this new slope and the given point to find the y-intercept:
y = mx + b
4 = (?)(2) + b
4 = ? + b
15/4 = b
Use the new slope and y-intercept to write the new linear equation:
Answer:
y = 1/8x + 15/4
Sorry if i'm wrong
seemed easy
Answer: -1 84/135
Step-by-step explanation:
- 8/9 (15) + 11/15(9)
= - 120/135 + 99/135
=219/135
= - 1 84/ 135
i hope this helps
