Step-by-step explanation:
Hi there!
Linear equations are typically organized in slope-intercept form: where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)
1) Determine the slope (m)
where the points given are and
Points (3,2) and (6,11)
Therefore, the slope of the line is 3. Plug this into :
2) Determine the y-intercept (b)
Plug in one of the given points and solve for b
Subtract 9 from both sides
Therefore, the y-intercept of the line is -7. Plug this back into :
I hope this helps!

4x+2y=)
equation (i) becomes-
4x + 6y =100
subtracting ii from iii
we get,
4y=96
y=24
∴ x=50- 3*24 /2 = 50-72/2= -11
2. x+2y=
-x -3y= -
adding i and ii
-y= -5
y= 5
∴ x=9-10
x= -1
