Answer:

Step-by-step explanation:
Equation of a line is given as 
Where,
m = slope of the line = 
b = y-intercept, which is the value at the point where the line intercepts the y-axis. At this point, x = 0.
Let's find m and b to derive the equation for the line.

Use the coordinate pair of any two points on the line. Let's use the following,
=> on the line, when x = 0, y = -2
=> on the line, when x = 4, y = 1
Plug in the values and solve for m



b = -2 (the line intercepts the y-axis at this point)
Our equation would be =>



You would add like terms so it would be 1x then you add 1 to 7 so you would get 8.. the you divide both sides by 1x and you'd get 8=x
Answer:

Step-by-step explanation:

Keep the variables in the left side & rest in the left side:




Hello,
The equation is y-2=4/5(x-8)==>y=4/5x-22/5 or 4x-5y=22

Answer: (4, 3)
Step-by-step explanation:
The formula for coordinate of the mid point is given as :
Mid point = (
,
)
= 9
= -1
= 9
= -3
Substituting the values into the formula , we have :
Mid-point = (
,
)
Mid-point = (
,
)
Mid - point = ( 4 , 3)
