Answer:y = -4.5x - 22
Step-by-step explanation:
The standard form of finding the equation of a line is expressed as y = mx+c
m is the slope
c is the y intercept
Get the slope:
m = y2-y1/x2-x1
Given the coordinates (-6,5) and (-4,-4)
m = -4-5/-4+6
m = -9/2
m = -4.5
Get the y-intercept
Substitute (-4,-4) and m = -4.5 into y = mx+c
-4 = -4.5(-4) + c
-4 = 18 + c
c = -4-18
c = -22
Get the required equation:
Recall that: y = mx+c
y = -4.5x - 22
Hence the required equation is y = -4.5x - 22

Answer: 80 men
Step-by-step explanation:
Let m represent the number of men , w , the number of women and c the number of children , then we have:
m : w = 4 : 5 ............... equation 1
w : c = 10 : 9 ............ equation 2
Multiply equation 1 by 2 so as to get the ratio m:w:c , that is
equation 1 becomes : m: w = 8 : 10
so the combine ration m : w : c is 8 : 10 : 9
The total ratio is therefore 8 + 10 + 9 = 27
number of men = ratio of men/ total ratio X 270
number of men = 8/27 X 270
number of men = 8 X 10
number of men = 80
The expression of that statement will be
2x - 5
8.394-2.199= 6.195 but rounded to the nearest hundred is 6.2
