Question

Which equation represents the slope-intercept form of the line below?

y- intercept (0,5)
slope- -3

Answer 1

For this case we have that the equation of the straight line in its generic form is given by:

`y = mx + b`

Where,

• m: slope of the line
• b: intersection with the vertical axis.

We have then for this case:

`m = -3\\b = 5`

Substituting values we have:

`y = -3x + 5`

Answer:

The equation that represents the slope-intercept form of the line is:

`y = -3x + 5`

Answer 2

y = -3x + 5

When creating a line in slope intercept form, the -3 always goes right next to the x after the equals sign. Also, the y intercepts y value (the second part of the parenthesis) just gets added on at the end of the equation.
