Step-by-step explanation:
no soloutions have the same slope but different intercepts so it cannot be d because the slopes are different.
if the two points are (9, 260) and (29.5, 530), calculate the slope of the line that runs through them.
A. 13.17
B. 12.25
C. 11.32
D. 10.42
Answers
Answer:
m = rise/run = 270/20.5 = 13.17
Step-by-step explanation:
Going from (9, 260) to (29.5, 530), we see that the horizontal change (in x) is 20.5 and the vertical change (in y) is 270. Thus, the slope is
m = rise/run = 270/20.5 = 13.17
Scarlett needs to order 6,318 binder clips for an upcoming conference. If the binder clips come in
boxes of 39, how many boxes should Scarlett order?

Plus why defuk she need that manny binder clip. Does she eat them
Answer:
6318 / 39 = 162 boxes.
This question does not really make sense because you ask how many boxes are needed, then say that the clips are coming in 39 boxes.
What value of y makes the equation 4x – 3y = 17 true, when x = 2?
Answers
Answer:
y = -3
Step-by-step explanation:
4x – 3y = 17
x = 2
4(2) - 3y = 17
8 - 3y = 17
-3y = 9
y = -3
Answer:
y= -3
Step-by-step explanation:
if x =2, substitute
4(2) - 3y = 17
8-3y = 17
(add 3y to both sides)
8= 17 + 3y
(subtract 17 from both sides)
8-17=3y
-9= 3y
(divide both sides by 3)
-9/3=y
y= -3

Step-by-step explanation:
We can graph this line using the equation given to us. The equation is in slope-intercept form, [tex]y=mx+b[/tex]. In this form, [tex]m[/tex] = slope and [tex]b[/tex] = the y-intercept.
So, we can tell that the slope is -[tex]\frac{1}{5}[/tex] and the y-intercept is (2,0).
We begin by plotting on the graph the y-intercept, (2,0).
The slope also equals the [tex]\frac{rise}{run}[/tex]. The slope is negative, so the line will slope down. From the point we have plotted, we will rise negative 1 unit. This means to move down 1 unit. From this point, we will run 5 units. Because the line is negative, we will move 5 units to the left, not the right. We land on point (5,1).
Now, we will draw a line from these two points. This is the line shown in the equation.
Good luck ^^
