What is the equation of the line that passes through the point (2, -1) and has a slope of -3?
Answer: y=-3x-7
Step-by-step explanation:
Y+1 =-3x-6
Answer:
y=-3x+5
Step-by-step explanation:
1. Put the equation into point-slope form: y-y1=m(x-x1)
Use the coordinates to put into y1 and x1 and use the slope to put into m. For y1 and x1, whenever there's a negative number in the provided coordinates, you'll need to change the subtraction sign into an addition sign because two negatives make a positive.
y+1=-3(x-2)
2. Distribute -3 to x-2 and subtract 1 from both sides.
y+1=-3x+6
y=-3x+5
