Question

Convert from Point-Slope Form into Slope-Intercept Form. Show your work!1. y + 1 = 7(x + 2) 2. y – 1 = –2(x – 1) 3. y – 2 = 1/4(x – 1) 4. y – 4 = 3(x – 3)

Answer 2

1. y+10=7(x+2) (applying the distributive law to the right side of the equation)

y= 7x+14-10 (substracting 10 in both sides of the equality)

y=7x+4

2. y-1=-2(x-1) (applying the distributive law to the right side of the equation)

y-1=-2x+2 (adding 1 in both sides of the equality)

y=-2x+2+1 (simplifying)

y=-2x+3

3. y-2=1/4(x-1) (applying the distributive law to the right side of the equation)

y-2=x/4 -1/4 (adding 2 in both sides of the equality)

y=1/4(x) -1/4+2 (simplifying)

y=1/4(x) +7/4

4. y-4=3(x-3) (applying the distributive law to the right side of the equation)

y-4=3x-9 (adding 4 in both sides of the equality)

y=3x-9+4 (simplifying)

y=3x-5
