Answer:
y= x+1
Step-by-step explanation:
The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.
Gradient of line = 
Using the above formula,
Gradient
Thus m=1. Substitute m=1 into the equation:
y= 1x +c
y= x +c
Susbt. a coordinate.
When x=3, y=4,
4= 3 +c
c= 4-3
c=1
Thus, the equation of the line is y= x+1.
What number is y equal to
Answer:
The coordinates of A would be (-1, 2)
Step-by-step explanation:
In order to find this, use the mid-point formula.
(xA + xB)/2 = xM
In this, the xA is the x value of point A, xB is the x value of point B, and xM is the x value of M. Now we plug in the known information and solve for xA.
(xA + 5)/2 = 2
xA + 5 = 4
xA = -1
Now we can do the same using the midpoint formula and the y values.
(yA + yB)/2 = yM
(yA + 10)/2 = 6
yA + 10 = 12
yA = 2
This gives us the midpoint of (-1, 2)
The bottom one is 90
And the top one is 100
V=190
