Write an equation of the line that passes through the point 4 comma 1 and has a slope of 2?
The general equation for a straight line is: y=mx+c
m being the gradient (slope), and c being the y intercept (which isn't important in this question)
So firstly, we substitute the slope into the rule which gives us:
y=2x+c
Then we substitute in the point (4,1), 4 being the x-value and 1 being the y-value. This means that when x=4, y=1, so if we put this into our equation:
(4,1) => 1=2x4+c
1=8+c
Now subtract 8 from both sides
-7 = c
Finally, substitute your m and c into the rule and you get your straight line equation:
y=2x-7

Is line k parallel to line h why or why not A line k passes through the points 4 comma 2 and negative 4 comma 4 A second line h passes through the points negative 8 comma1 and 8 comma negative 3?
Line k: (4, 2), (-4, 4)slope mk = (4 - 2)/(-4 - 4) = 2/-8 = - 1/4Line h: (-8, 1), (8, -3)slope mh = (-3 - 1)/(8 - -8) = -4/16 = - 1/4Since both lines have equal slopes, - 1/4, the lines are parallel.
How do you write one thousand and nineteen in numbers?
Depending upon the particular context, you might write 1019, or you could put in a comma and write 1,019. It will mean the same, either way.
How do you write five million six hundred and twenty?
5,000,620 (the first comma FROM THE RIGHT says "thousand", but here there are no thousands, so we don't say anything. The second comma FROM THE RIGHT says "million").

What would the equation of a line be if it went through the point 2 comma 2 and its yintercept was 10?
We know that the line passes through points (2, 2) and (0, 10) (since the y-intercept is 10).Using these two points, we can find the slope of the line,m = (10 - 2)/(0 - 2) = 8/-2 = 4/-1 = -4.Now by using the slope, m = -4, and the y-intercept, 10, we can write the equation of the line in the slope-intercept form, y = mx + b which isy = -4x + 10.
One line passes through points 9 comma 0 and 5 comma 3. A second line passes through 0 comma 0 and .5 comma 3. At what point do the two lines intersect?
Equation of a line through point (x0, y0) with gradient m is given by: y - y0 = m(x - x0) the gradient m between two points (x0, y0) and (x1, y1) is given by: m = change_in_y/change_in_x = (y1 - y0)/(x1 - x0) → equation of line through (9, 0) and (5, 3) is: y - 0 = ((3 - 0)/5 - 9)) (x - 9) → y = (3/-4) (x - 9) → 4y = -3x + 27 → equation of line through (0, 0) and (0.5, 3) is: y - 0 = ((3 - 0)/(0.5 - 0)) (x - 0) → y = (3/0.5)x → y = 6x This gives two simultaneous equations which when solved give the point where the two lines intersect: y = 6x → 4y = 24x → 24x = -3x + 27 → 27x = 27 → x = 1 → y = 6 × 1 = 1 → point of intersection is (1, 6)
Is it a colon or comma at the end of a salutation?
It is almost always a comma, but rarely I have seen a colon. When you are writing a formal letter, it is a comma, but if you were to write a informal letter to a friend, it doesn't really matter. For all of the letters I write I use a comma, and so does everybody else I know.
Do you use a comma writing thanks a lot?
No, a comma is not necessary when writing "thanks a lot." You can simply write "Thanks a lot" without a comma.
Can you write the word 'and' directly following a comma?
The point of a comma is to establish the meaning of an "and or but or any of these conjectives". So there is no need to use and after a comma, as its not proper grammer.e.g. ,and / ,but / ,therefor Hope this helps,
