Answer:
y + 4 = -2(x - 3)
Step-by-step explanation:
Use the point-slope formula y - k = m(x - h). Substitute -2 for k and 3 for h, as well as -2 for m:
y + 4 = -2(x - 3).
Answer:
Step-by-step explanation:
y = 2x^2 - 12x +19 Put brackets around the 1st 2 terms. Take 2
y = 2(x^2 - 6x ) + 19 Take 1/2 of the 6 square it and add inside the brackets
y = 2(x^2 - 6 + (6/2)^2) +19 Subtract 2 *9 from the 19. Express 1st 3 terms as ( )^2
y = 2(x- 3)^2 + 19 - 18
y = 2(x - 3)^2 + 1
