The answer would be 4 x 4 = 16+14= 30
Y=mx+b is our base equation
m=slope, so let's find that first:
m= change in y/change in x
So between the points (-1,-2) and (3,4),
The y values, -2 and 4, have a difference of 6. The x values, -1 and 3, have a difference of 4. This makes our slope 6/4 (or 3/2 simplified)
Now our equation is
Y=3/2x + b
We still need to find b
To find b, we can substitute a point given to us. Let's use (3,4) just to avoid negatives.
4=3/2(3) + b
Multiply
4=9/2 + b
Subtract 9/2 from both sides
-1/2=b
Now let's put it all back together!
Y=3/2x-1/2 Is the answer.
I hope this Helps!
Answer:
A
Step-by-step explanation:
Answer:
y=9 7/15
Step-by-step explanation:
y + 3 7/15 = 12 14/15 - 8/15
y + 3 7/15 = 12 14/15
y + 3 7/15 = 12 14/15
- 3 7/15 - 3 7/15
y = 9 7/15
