Answer:
7. a) slope = 5
7. b) slope = 1/2
8. slope = 1
Step-by-step explanation:
slope = rise/run
rise is the vertical change, run is the horizontal change
7. a)
Pick any two points on your line. (0,0) and (1,5) are easy to work with.
The vertical change between the two points is 5
The horizontal change between those points is 1
so slope = 5/1 = 5
7. b)
Again, you can use (0,0) as one of your points. The point (2,4) is good as the second.
slope = 4/2 = 1/2
8. We don't have a graph, but we are given two points to work with, (1,4) and (5,8). Use the formula given...
m = slope = (y2-y1) / (x2-x1)
= (8 - 4) / (5 - 1)
= 4/4
= 1
I hope that helped!
Answer:
C
Step-by-step explanation:
I am pretty sure but get another answer just to be sure.
The correct answers are A, D, and E.
D. it represents the product of two rational numbers and is equivalent to an irrational number
Answer:
y=2x+7
Step-by-step explanation:
The slope of the new line is 2 because that is the opposite of -1/2
To find the equation of the line, plug the points (-2,3) into point-slope form:
y-y1=m(x-x1).
y-3=2(x+2)
Multiply (x+2) by 2 and simplify to get the final answer.
y-3=2x+4
y=2x+7
