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

Find the gradients for line A and B.<br><br> See pic attached
pogonyaev
Gradient is the difference between the y-axis and the x-axis
Gradient = y2-y1/x2-x1
Choose any two point making a triangle
Line B (0,8) (4,0)
This makes a triangle please go look at the graph once again! The the triangle should not have half squares but full!
Line A (5,14)(2,2)
Now plug in the variable
The difference between the Y and X
Line B 0-8/4-0
Line B gradient =-2
Line A 2-14/2-5
Line A gradient = +4

Finalized answer
Line B gradient = -2
Line A gradient = +4
