Answer:

(a) y = -4x + 4 (b) y = 2x + 3

<u>solving steps:</u>

note: m refers to slope and y₁ to y point and x₁ to x point

a)

coordinates: (2,-4)

slope: -4

equation:

y - y₁ = m(x - x₁)

y - -4 = -4(x-2)

y = -4x + 8 - 4

y = - 4x + 4

b)

coordinates: (1,5), (-1,1)

slope: $\sf \dfrac{y-y_1}{x-x_1}$

$\sf \dfrac{1-5}{-1-1}$

2

equation:

y - y₁ = m(x - x₁)

y - 5 = 2(x - 1)

y - 5 = 2x - 2

y = 2x - 2 + 5

y = 2x + 3

Find the x and y intercept of y= -2(x-3)^2+4

Neko [114]

Y intercept occurs when x = o so it is -2(0-3) + 4 = -2

x intercepts:-

-2(x - 3)^2 + 4 = 0

(x - 3)^2 = -4/-2 = 2

x - 3 = +/- sqrt2

x = 3 + sqrt2 and 3- sqrt2
