A40=a1 +(40-1)r
in this case r is 3 beceause -2+3 will be 1 etc
a40=-2 +39*3
Answer:
x= -2
Step-by-step explanation:
7x-3=4x-9
3x-3= -9
3x= -6
x= -2
Answer:
Step-by-step explanation:
The equation of the line is written in the slope-intercept form, which is: y = mx + b, where m represents the slope and b represents the y-intercept. In our equation, y = 6x + 2, we see that the slope of the line is 6.
Hope this helps :)
We are given two points on a line. First we need to find the slope of the line using these two points.
The given points are (6, 1) and (5, 4). The slope (m) of the line will be:

Using the slope and the point (6,1) we can write the equation in point slope form as:
y - 1 = -3(x -6)
y = -3x + 18 + 1
y = -3x + 19
In standard form, the equation will be:
3x + y = 19
Answer: Section formula
Step-by-step explanation:
Given
The line segment AB with endpoints
and
is divided by a point X in the ratio 1:2
To verify that X divides the line segment in the ratio 1:2, we will use section formula. Section formula tells the coordinates of the point which divide the line segment in the certain ratio or vice-versa.
We will assume that X divides AB in k:1 and insert the values in the section formula. If the ratio k:1 comes out to be 1:2, then it verifies the claim.
