How can you write the equation of the

line?
(: before the lady in the video shows
you :)
y 5x = 3
y = 3x - 5
y = -5x + 3
y + 3 = -5x

Answer is
Part 1) y = 3x -5
Part 2) y = 2x + 7

Step by step

Part 1 - they gave you slope of 3 and y intercept of -5

Your equation set up is y= mx + b

M is slope and b is y intercept so

y = 3x - 5

Part 2 - they give you (-1, 5) and slope (m) 2

Your formula is y - y1 = m (x - x1)

y - 5 = 2 (x - -1)

Distribute

y - 5 = 2x + 2

Add 5 to both sides to solve for y

y -5 +5 = 2x +2 +5

Combine

y = 2x + 7 is your answer
