Write the equation in point slope form of the line that has a slope of -3/2 and passes through (4, -3)

• y - 4 = -3/2(x + 3)

• y + 3 = -3/2(x+ 4)

• y - 3 = -3/2(x + 4)

• y + 3= -3/2(x - 4)

Given that the slope is  -4 and the y intercept is -4 what is the equation of the line?

• y = 4x - 4
• y = -4x - 4
• y = -4
• y = -4x + 4
