You have the right idea so far, but you forgot to finish it up.
Point slope form is
y - y1 = m(x - x1)
where m is the slope, and (x1,y1) is the point the line goes through. As you can see, we have infinitely many choices for (x1,y1). If you use the y intercept point (0,5), then
y - y1 = m(x - x1)
y - 5 = -1(x - 0) ..... this is one of infinitely many possible answers
OR
If you use the point (2,3), then we'd say
y - y1 = m(x - x1)
y - 3 = -1(x - 2) ..... which is another possible answer
There are infinitely many other choices, but I'm only picking the points in which your teacher has shown as big dots.
By the way, nice work on getting the correct answer for the slope-intercept form.
Answer:
The equation must include -8 as the slope
Step-by-step explanation:
Hi there!
Two key points to keep in mind:
- Linear equations are typically organized in slope-intercept form:
where m is the slope and b is the y-intercept (the value of y when x is 0). - Parallel lines always have equal slopes
Given the equation y=-8x+6, we can identify that -8 is in the place of m in y=mx+b, making it the slope.
For a line to be parallel to y=-8x+6, it would have to have a slope of -8 as well. This is the only quality a line needs to be parallel to this given line.
I hope this helps!
Answer:
a: The percentage change from 1/3 to 2/3 is 100 %
b: The percentage change from 1/3 to 1/6 is 0 %
Step-by-step explanation:
use this formula:
((y2 - y1) / y1)*100 = your percentage change
(where y1=start value and y2=end value)
((2/3 - 1/3) / 1/3) * 100 = 100 %
_________________________________
((y2 - y1) / y1)*100 = your percentage change
(where y1=start value and y2=end value)
((1/6 - 1/3) / 1/3) * 100 = 0 %
