Question

Write the equation of a line that goes through point (0,8) and has a slope of 0

Answer 1

I think the answer is B it would be a vertical line with the rise/run for finding slope

Answer 2

The equation of a line that goes through point (0,-8) has a slope of 0 is $\bold{y=-8}$

Option - c

Solution:

Given, the slope of line passing through (0, -8) is 0

Point- slope form of a line is $y - y_1 = m (x - x_1)$

where m is the slope; $y_1= -8 \text{ and } x_1= 0$

On substituting the values we get,

$y-(-8)=0\times x-0 \rightarrow y+8=0$

$\bold{\Rightarrow y=-8}$

Thus, the required equation is $y=-8$

Slope:

The slope of a line is a number that measures its "steepness", usually denoted by the letter m. It is the change in y for a unit change in x along the line.
