Answer:
see explanation
Step-by-step explanation:
the equation of a line in slope-intercept form is
y = mx + c ( m is the slope and c the y-intercept )
(1)
y = 3x + 4 is in this form
with slope m = 3 and y-intercept c = 4
(2)
y = - x - is in this form
with slope m = - and y-in tercept c = -
(3)
rearrange 3x + y = - 4 into slope-intercept form
subtract 3x from both sides
y = - 3x - 4 ← in slope-intercept form
with slope m = - 3 and y-intercept c = - 4

The formula determine the distance from C to D is:
<h3><u>
Step-by-step explanation:</u></h3>
The formula that can be used to determine the distance from point C to point D is:
We know that distance between two points A(a,b) and B(c,d) is equal to the length of the line segment AB and is calculated by the help of the formula:
So, here we have:
(a,b)=(a,b) and (c,d)=(0,b)
Answer:
The vertex is at ( 3.5, -0.25)
and the axis of symmetry is x = 3.5.
Step-by-step explanation:
Convert to vertex form:
y = x^2 - 7x + 12
y = (x - 3.5)^2 - 3.5^2 + 12
y = (x - 3.5)^2 - 0.25
y = (x - 3.5)^2 - 0.25.
So the vertex is at ( 3.5, -0.25)
and
the axis of symmetry is x = 3.5.
