Find slope first:
m =y2-y1/x2-x1
m = 1--2/2--2
m = 3/4
Select a point, insert your slope, & put it into point slope form:
y-y1 =m(x-x1)
Your final answers are:
y-1=3/4(x-2)
OR
y+2 =3/4(x+2)
A is your answer im pretty sure took the test
Hello from MrBillDoesMath!
Answer:
Choice A, 1/4
Discussion:
Consider the perfect square
(x + a)^2 = x^2 + (2a)x + a^2
The constant term (a^2) equals 1/2 the coefficient of x (i.e. 2a), squared.
Let's apply this idea to x^2 + x
x^2 + x = => as 2 * 1/2 = 1
x^2 + ( 2 * 1/2)x =
( x^2 + (2* 1/2)x + ( 1/2) ^2 ) - (1/2) ^2 =
as constant term to add is 1/2 coefficient of x (that is, 1/2) and
(1/2)^2 - (1/2)^2 = 0
(x + 1/2) ^ 2 - (1/2)^2
In other words add the constant (1/2)^2 = 1/4, which is Choice A.
Thank you,
MrB
A point in the form of (0, number) is the y - intercept. That's because there is movement in the x -direction and the point is plotted on the y -axis. Our number in the ordered pair is the y-intercept - in this case, 10.
Slope intercept form is y = mx + b where m is the slope and b is the y-intercept. We are told the slope is 9 and we found the y-intercept, 10. 9 goes in for m, 10 goes in for b.
Thus the line (in slope intercept form) is y = 9x + 10.
