Answer:
y = -4x + 11
Step-by-step explanation:
Equation of a line is
y - y_1 = m ( x - x _1)
We are provided
Slope = m = -4
Points = (x _1 , y_1) = (2, 3)
Insert the values
y - y_1 = m( x - x_1)
y - 3 = -4(x - 2)
Open the bracket with -4
y - 3 = -4x + 8
y - 3 -8 = -4x
y - 11 = -4x
Following this equation of a line
y = mx + C
y - intercept point y
m - slope
x - intercept point x
C - intercept of the line
y - 11 = -4x
y = -4x + 11
Therefore, the equation of the line is
y = -4x + 11
Answer:
1/2
Step-by-step explanation:
y1-y2/x1-x2
1-2/3-5=1/2
Answer:
So i found the teacher notes after hours of looking here are the exact answers so i would recommend changing the wording.
Part A: Ordered pairs in the form (mb, kmh): (1,000, 100) and (960,180) Let X be the barometric pressure and Y be the wind speed.
Slope= (180-100)
---------------- = -2
(960-1000)
Formula: y=-2(x-1000)+100
Part B: y=-2(980-1000)+100=140
140 kmh is reasonable. Because 980 mb is halfway between 960 mb and 1000 mb, we should expect a wind speed halfway between 180 kmh and 100 kmh.
Part C: The wind speed intercept is (0,2100) [or (2100,0) if written that way.] This means that when brometric pressure is 0 mb, then the wind speed would be 2100 kmh. However in the context of real weather, this is an impossible situation.
Part D: The slope means that every decrease of 2 kmh in wind speed corresponds to a 1 mb increase in barometric pressure.
