Answer:
Your answer will be
y=2x-15.5
Step-by-step explanation:
Hi, there you must know the slope-intercept form which is
y=mx+b
m=slope
b=y-intercept
You can also use
the slope formula which is
in this case
it will look like this
=
=-2
So the slope is -2
Now we will find the y-intercept
-7.5=2(4)+b
-7.5=8+b Subtract 8 both sides
-15.5=b
Your y-intercept is -15.5
Hope this helps
Answer: 94.5
Step-by-step explanation:
If average of 9 students is 94, their total will be 94x 9 = 846
If the 10th student scores 99, the new total is 846 + 99 = 945
So, the new average will be
945/10 = 94.5
