Answer:
See below:
Step-by-step explanation:
To find the slope, we use the following formula:
For this case, we can use (6,60) as the first set of points.
We can use (4,70) as the second set of points.
Now, we can use the formula, 70-60 is for the top of the fraction (10)
We can do 4-6 to find the bottom, which is (-2)
Now, if we add the fraction back we get -> 10/-2 which is -5 for slope!
To find out the y intercept, it in simple words is "What is y when x is 0?".
We can do that by using the slope intercept formula: .
Once we insert our slope which is -2 we get:
We can now substitute a point, lets use (6,60) so we can find out b.
We now get the equation: .
If we solve for that we get 90!
Once we input that, we get,
Now we put in x as 0 and we get our y intercept as 90!

Answer:
The equation of line with given points is y - 4 = 3 ( x + 2 ) .
Step-by-step explanation:
Given as :
The points of line are ( 1 , 13 ) and ( - 2 , 4 )
The point slope intercept equation of line is
y - = m ( x -
)
Where m is the slope of line
So , Slope , m =
Or, m =
Or, m =
∴ m = 3
Now The equation of line is
y - = m ( x -
)
Or. y - 13 = 3 ( x - 1 )
Or, y - 13 = 3 x - 3
Or, y = 3 x - 3 + 13
∴ y = 3 x + 10
I.e y - 4 = 3 x + 6
Or, y - 4 = 3 ( x + 2 )
Hence The equation of line with given points is y - 4 = 3 ( x + 2 ) . Answer
