Find the slope of the line. (2, 1.5) (-4, -3)
Answer:
3/4
Step-by-step explanation:
The way to find slope is by using the slope formula (y1 - y2)/(x1-x2) where you have two points (x1, y1) and (x2, y2). Next, substitute these points into the equation and you would get (-3 - 1.5)/(-4-2), which is -4.5/-6. -4.5/-6 = 3/4, so the slope is 3/4.

Can someone help me with my math if you help me i will give you a brainliest
Answer:
Step-by-step explanation:
So its difficult to show
Y= X-6 so what ever x is, y is six less than that so
X= -4 Y= -10
X= 0 Y=-4
X=4 Y=0
X=8 Y= 4
Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them
Y= 4/3x -2 so whatever x is y is 4/3 and 2 less then that
X=-4 Y= -5
X=0 Y= -2
X=4 Y=1
X= 8 Y= 4
Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them
Y= -2
Find minus 2 on the y axis and draw a horizontal line through it all the way across the grid.
Y= 2+ 1/4x so whatever x is y is 1/4 of x add 2
X=-8 Y= 0
X= -4 Y = 1
X=0 Y=2
X=4 Y=3
X=8 Y=4
Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them
Do this method for 9
y = 2x -3 so whatever x is, y is 2 times that -3
y=2x +1 so whatever x is y is 2 times that +1
y= 2x so whatever x is y is 2 times that
Then plot the answers on a graph like co-ordinates (x,y) and draw a straight line through them
Make sure to label each line
Hope this helps

In the weeks after a chick hatches, its mass increases by a factor of 2.5 to become 180 grams. What is the chick’s mass at hatching?
Write and solve an equation to show the answer.
Explain when to use division and when to use multiplication to solve an equation. Give examples to support your answer
Answer: 1,796
Step-by-step explanation:
We are given that : At the chicken ranch this morning there were 7,149 chicks.
i.e. The number of new chicks before today = 7,149
Later today some more chicks hatched. now the ranch has 8,945 chicks.
i.e. The number of new chicks after today = 8,945
Then, By Subtraction operation
Number of new chicks hatched today = ( Number of new chicks after today) - (Number of new chicks before today )
= 8,945- 7,149 = 1,796
Therefore , the number of new chicks hatched today = 1,796
