Answer:
w=0
Step-by-step explanation:
We know a point (3,1) and the slope (-8/3), so we can use point-slope form, which is y-y1=m(x-x1)
For reference, y1 is the y in the point, m is the slope, and x1 is the x in the point
So we subsitute it
y-1=-8/3(x-3)
do distributive prop.
y-1=-8/3x+8
add 1 to both sides
y=-8/3x+9
This is the equation of the line.
Now to find w, which is the x value.
The point will pass through line, so we can susbtitute the point into the equation.
9=-8/3x+9
subtract 9 from both sides
0=-8/3x
multiply by -3/8 on both sides (the reciprocal of -8/3), we need to isolate x
0=x
x=w
therefore, w=0
Hope this helps!
Put the equation
into the form y = ( x − h )^2 + k
Given equation is
We apply completing the square method
we take coefficient of middle term and then divide by 2 and then square it
coefficient of middle term is 26
Divide by 2, it becomes 13
then we square it (13)^2 = 169
Add and subtract 169
We got the equation in vertex form
Answer:
rise 4, run -2. the gradiant is 2
Step-by-step explanation:
(X1,Y1)___(X2,Y2)
| | | |
(-2,2)_____(0,6)
X1-X2, Y1-Y2.
-2-0= -2= (-2,_)
2-6= 4= (_,4)
(-2,4)
