Q # ..18 I need your help

Answer 1

Answer: y = -5x - 3.

Explanation:

When you know the slope and the y-intercept you can directly write the slope-intercept equation of the line.

The slope-intercept equation of the line has the form: y = mx + b, where m is the slope and b is the y-intercept.

Here you know m = -5 and b =  -3, hence you just have to substitute those values in the general slope-intercept form, which is:

• y = -5x - 3.

That equation represents the line, which means tha every point in the line will be an ordered pair of the function. For example:

  x            y = -5x - 3

- 10          -5(-10) - 3 = 50 - 3 = 47

  0            0 - 3 = - 3 (this is the y-intercept)

10            -5(10) - 3 = - 50 - 3 = - 53
