What is the equation for the points (-3,1) and (9,7)
Scorpion4ik [409]

Answer:

The equation of line with given points is 2Y - X - 5 = 0

Step-by-step explanation:

Given points are ( - 3 , 1)   and   (9 , 7)

Equation of line is y = mx +c

where m is the slop of line

Now m = \frac{y2 - y1}{x2 - x1}

Or,    m = \frac{7 - 1}{9 + 3}

so, slop = \frac{6}{12}

∴   slop = \frac{1}{2}

Now the equation of line with points ( -3 , 1) and slop m is :

Y - y1 = m ( X - x1)

Or, Y - 1 =  \frac{1}{2} (X + 3)

Or, 2Y - X - 5 = 0

Hence The equation of line with given points is 2Y - X - 5 = 0 Answer

qaws [65]
After striking a pair of arcs from each endpoint of a line segment, just join the intersection point of the 1st pair (above the segment) with the intersection point
of the 2nd pair (under the segment)
And this is how you construct the segment's perpendicular bisector

What is the measure of W the parallelogram shown?
nexus9112 [7]

Answer:

148 degrees

Step-by-step explanation:

For a parallelogram, angles on the same side sum up to be 180

what this simply means is that they are supplementary

Mathematically, we have it that;

X + W = 180

W = 180 - X

W = 180 -32

W = 148 degree
