So one dot you could make is at -1 on the y axis because your y intercept (the -1 in y=3/4x-1). Another dot you could make if you follow the slope is a point up three and over 4 (slope is rise over run).
Picture explanation:
Hope this helps!
Slope equals 2
Form = y-y1= m(x-x1)
Y-1=2(x+1)
Answer: 12 out of the 32 would be boys. Hope this helps.
The answer looks like it's A.
Answer:
-5.7
Step-by-step explanation:
OUR EQUATION IS A QUADRATIC EQUATION
Let Δ be our dicriminant :
- a= 1
- b= 5
- c= -4
- Δ= 5²-4*1*(-4) =25 +16 =41≥0
- so we have two solutions x and y
- x= (-5-√41)/2 = -5.7
