A line passes through the points (-1, -6) and (-4, 3). What is the equation of this line in slope-intercept form?

A) y = -3x - 9
B) y = x + 19
C) y = 9x + 7
D) y = x - 7

Since we have two ordered pairs, we can find the slope by plugging them into (y2-y1)/(x2-x1) which translates to (3-(-6))/(-4-(-1))=9/-3=-3

Since the slope is -3, we have the equation y=-3x+b, but we don't know b. So we plug in values for x and y and solve for b.

-6=-3(-1)+b

-6=3+b

-9=b

So the y-intercept is -9 and the full equation is y=-3x-9 which means A is the only correct answer.

Hope this helped!
