Answer:
<h3>y - 3 = 2(x+1)</h3>
Step-by-step explanation:
The equation of the line in point slope form is expressed as;
y - y0 = m(x-x0)
m is the slope
(x0, y0) is a point on the line
Get the slope;
Given the points (-1,3) and (1, 7)
m = y2-y1/x2-x1
m = 7-3/1+1
m = 4/2
m = 2
Substitute the point m = 2 and the point (-1, 3) into the formula above as shown;
y - y0 = m(x-x0)
y - 3 = 2(x-(-1))
y - 3 = 2(x+1)
Hence the required equation is y - 3 = 2(x+1)

Step-by-step explanation:
Answer: C)
Step-by-step explanation:
The given formula :
To rearrange the formula to find the formula for r , first we multiply both sides with (a-r), we get
Divide both sides by S , we get
Subtract a on both sides , we get
Multiplying (-1) on both sides , we get
Hence, the correct answer is : C)
Four million, six hundred thousand twenty-two, nine hundred nine.
