ANSWER
EXPLANATION
Since the parabola has the (0, 0) and the directrix at y=2.
The equation is of the form
where (h,k) is the vertex.
The vertex is half way between the directrix and the focus.
The vertex will be at (0,1)
and is the distance from the vertex to the focus which is 1.
6) slope is 1, y-intercept is 3, equation in slope-intercept form:
7) Slope of the line that goes through the points (3,9) and (-5,3) is
8) Slope = m=
y-intercept = b= -4
Step-by-step explanation:
6) Create table of coordinate points:
x y
-2 1
-1 2
0 3
1 4
2 5
Identify the slope:
Using formula:
Putting values:
So, slope is 1
Identify y-intercept.
y-intercept is found when x=0, so, looking at the table when x = 0, y= 3 so, y-intercept is 3
Equation in the form: y=mx+b
here m is slope and b is y-intercept
Putting values:
So, equation in slope-intercept form:
7) Find the slope of the line that goes through the points (3,9) and (-5,3)
Using formula:
Putting values:
So, slope of the line that goes through the points (3,9) and (-5,3) is
8) What is the slope and y-intercept of the following equation:
The equation is in slope-intercept form
The general equation of slope-intercept form is:
where m is slope and b is y-intercept
Comparing both equations we get:
Slope = m=
y-intercept = b= -4
