Question

Write an equation for the line given that m=0 and the y intercept is (0,-2)

Answer 1

Answer:

$\boxed{y=-2}$

Step-by-step explanation:

$The \ graph \ of \ the \ equation: \\ \\ y=mx+b \\ \\ is \ a \ line \ whose \ slope \ is \ m \ and \ whose \ y-intercept \ is \ (0, b)$

In this problem, this line has a slope $m=0$, that is, this is an horizontal straight line. The intercept is the point $(0,-2)$, so $b=-2$. Finally, by substituting these values we have:

$y=-2$

Lastly, this solution is shown in the figure below.

Answer 2

Answer:

y= -2

Step-by-step explanation:

The graph equation is y=mx+b. {The b is the y-intercept (0,b)}. There is no slope (mx) because the line doesn't go up or down. The y-intercept is (0,-2) so b=-2.  

y=mx+b

y=0+-2

y=-2

The answer is y=-2
