There is a line whose slope is –2 and whose y-intercept is –9 What is its equation in slope-intercept form?

Answer 1

slope intercept form is y=mx + b, where m is slope and b is the y intercept.

we are told the slope is -2, so m = -2

we are told the y-intercept is -9, so b = -9

the equation of the line is thus y = -2x-9
