Select the equation that represents a lone in which intercepts the vertical axis at b. assume m≠0, b ≠ 0, and m≠b.
Tema [17]

Answer:

Option 'C' is correct.

Step-by-step explanation:

We know that the slope-intercept form of the line equation

y = mx+b

where

  • m is the slope
  • b is the y-intercept

We are given that an equation that represents a line in which intercepts the vertical axis at b, assuming m≠0, b ≠ 0, and m≠b.

As the line intercepts the vertical (y-axis) at b.

Therefore, 'b' is the y-intercept of the line.

Also, the slope is m.

Thus, according to the slope-intercept form of the line equation, the equation is:

y = mx+b

Therefore, option 'C' is correct.

<span>(x + 12)(x - 10) </span>

<span>For the shorter side: </span>
<span>x - 10 = 0 </span>
