Answer:
y = -2.5 x + 6.5
Step-by-step explanation:
The equation of a line in slope-intercept form is written as
y = mx + b where m is the slope and b is the y-intercept.
a) We can find the slope of the line passing through (-1,30 and (-4, 5) by subtracting the y coordinates and dividing the difference by the difference if the x coordinates:
m = (5 - 3 ) = 2
-4 - (-1) -3
Now use this slope and substitute the coordinates of either of the given points to find the y-intercept, b . Let's use (-1,3):
y = mx + b
3 = -2 • -1 + b
3
3= 2 + b
3
7 = b
3
The equation of the line will be y = -2 x + 7
3 3
b) Using y = mx + b, we can substitute -2.5 for the slope and use the point to find the y-intercept:
y = -2.5x + b
1.5 = -2.5 • 2 + b
1.5 = -5 + b
6.5 = b
The equation of the line will be:
y = -2.5 x + 6.5
Answer: 135%
Step-by-step explanation: Given
Europe = 35%
Asia = 10%
Australia* = 20%
North America = ?
To find
Europe + Asia + Australia =
35% + 10% + 20% = 65%
Then the total subtracted from the given
200 - 65 = 135
Therefore,
North America = 135%
Confirm
To make sure that is the correct answer, add it all together.
35 + 10 + 20 + 135 = 200
Which means it is correct.
