Write the equation of a line with a slope of - 2 and a y-intercept of 5:

A) - 2 + y = 5

B) 2x - y = 5

C) y = - 2 + 5

D) y = 5x - 2

The equation of a line with a slope of - 2 and a y-intercept of 5 is y = - 2x + 5

Solution:

Given that slope is - 2 and y-intercept is 5

We need to find the equation of line

The equation of line when slope and y-intercept is given can be calculated using "slope-intercept form"

The slope intercept form is given as:

y = mx + b

where "m" is the slope of line and "b" is the y-intercept

Plugging the given values in slope intercept form, we get

y = - 2x + 5

Thus the required equation of line is found

Answer: y = - 2x + 5, so C (you probably just forgot to put the x)

Explanation: y = mx+b m represents the slope, b represents the y intercept
