60 POINTS PLEASE HELP FAST!!!! write the equation of a line in standard form that passes through the points (-4,-1) and (1.5,2)
1 answer:
You find your slope with the equation
(y2-y1)/(x2-x1)
(-1-2)/ -4-1.5)
(-3)/(-5.5)
.54x is your slope
you then plug that into your equation.
y=mx+b
y=.54x+b
you substitute one of our coordinates.
(-4,-1)
-1=.54(-4)+b
-1=-3.45+b
+3.45
2.45=b
your equation is
y=.54x+2.45
standard form
y-.54x=2.45

Answer:
c) x= 15
d) x= 5
Step-by-step explanation:
c)4x + 5+ 7x +10=180
solve it like usually
for d) 3x + 15+12x=90
Let x = The age of Michael
Let 2x-3 = The age of Michaels cousin
X+2x-3=46
x=16+1/3
X = 49 years
I think that’s the answer I’m not 100% sure though
Answer:
C. 15 units,
Step-by-step explanation:
The y coordinates are both 39 so the line joining the 2 points is a horizontal line.
Distance = 18-3 = 15.
Answer:
C
Step-by-step explanation:
I haven't done this math in years but from what I remember this should be the correct answer.
60,40,35,45,39
Put in order from least to greatest
35, 39, 40, 45, 60
Range = Max - Min
Range = 60 - 35
Range = 25
Answer
D) 25
