Answer:
The equation of the line would be y = .5x + 2.5
Step-by-step explanation:
In order to find this, we must first find the slope of the equation.
m (slope) = (y2 - y1)/(x2 - x1)
m = (2 - 3)/(-1 - 1)
m = -1/-2
m = .5
Now that we have the slope, we can use either point in point-slope form to get the equation.
y - y1 = m(x - x1)
y - 3 = .5(x - 1)
y - 3 = .5x - .5
y = .5x + 2.5
ANSWER
EXPLANATION
We can see that, the difference in y-values from the table is 3
Also the difference in the x-values is 3.
Hence the slope is
Let y=mx +c be function equation.
We put m=1 to get,
From the table when x=2, y=10.
This implies that,
Hence the function equation is
Answer:
D
Step-by-step explanation:
the answer would be (x^2+1)*(x-4)
step by step
x^3+ 4x^2+x+4
X^2(x+8)+ 1*(x+4)
(x+4)(x^2+1)
Answer:
5.25 or 5 1/4
Step-by-step explanation:
rate of change = slope = m = rise ÷ run
21 ÷ 4 = 5.25 or 5 1/4
