Answer:

Step-by-step explanation:
The equation of a straight line is

Where b is the y-intercept and m is the slope.
We substitute m=1 and b=10 to get:

This is called the slope-intercept form of the equation of a straight line.

The answer is -2 to your 8th grade algebra question hope it is right
Answer:
P = (2, 3)
Step-by-step explanation:
P is a local minimum, so can be found from the upper zero of the derivative.
y' = 0 = 3x^2 -8x +4
0 = (3x -2)(x -2)
x = 2/3, x = 2
So, the x-coordinate of P is 2. The y-coordinate is found by evaluating the function:
y = ((x -4)x +4)x +3 = ((2 -4)2 +4)2 +3 = 3
The coordinates of P are (2, 3).
