What is The equation of the line that passes through the point (4,8) and has a slope of 0

y = 8

Step-by-step explanation:

Plug in the point and slope into the equation y = mx + b to solve for b:

8 = 0(4) + b

8 = b

Then, plug this back into the equation:

y = 0x + 8

y = 8 will be the equation

y=8

Step-by-step explanation:

concept to know: when it is a horizontal line, the slope is zero, when it is a vertical line, the slope is undefined.

If it is required to have a slope of 0, then it is a horizontal line.

y=b (this is the equation for some line that slope is 0)

We then should find the b, or the y-intercept

The question did not provide us with a point of y-intercept, BUT since it is a horizontal line, the y value of any point is the same, including y-intercept (when x value is 0)

Therefore, the y-intercept will be (0, 8), and the equation will be

y=8

part a: 1.08

part b: 27.59
