Find the slope and y-intercept of the line through the points (-3,-4) and (0,-1)​

Answers

Answer:

Slope=1, y-intercept=-1.

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-1-(-4))/(0-(-3))

m=(-1+4)/(0+3)

m=3/3

m=1

y-(-4)=1(x-(-3))

y+4=x+3

y=x+3-4

y=x-1

y=mx+b where m=slope and b=y-intercept

so you have slope of 1 and y-intercept of -1

Variable y varies directly with variable x, and y = 6 when x = 9. What is the value of x when y = 18?

Answers

x and y are proportional hence when y is multiplied by a number, x is multiplied by the same number.

18=6*3 hence when y=18,x=9*3=27

x=27
so you can set up a proportion like
x/y=x/y
9/6=x/18
simplify 9/6=3/2
3/2=x/18
multiply both side by 18
(3x18)/2=x
54/2=x
x=27

Answers

5.48 to the nearest tenth is 5.5
9.63 is closest to 9.6
17.24 is closest to 17.2

5.5+9.6=15.1
17.2-15.1=2.1
