F(-4)=8 and f(-1)=4 write the linear equation
kobusy [5.1K]

f(-4)=8\to(-4,\ 8)\\\\f(-1)=4\to(-1,\ 4)

The point-slope formula of a line:

y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}

Substitute:

m=\dfrac{4-8}{-1-(-4)}=\dfrac{-4}{3}=-\dfrac{4}{3}\\\\y-8=-\dfrac{4}{3}(x-(-4))\\\\y-8=-\dfrac{4}{3}x-\dfrac{16}{3}\ \ \ \ |+8\\\\y=-\dfrac{4}{3}x-\dfrac{16}{3}+\dfrac{24}{3}\\\\y=-\dfrac{4}{3}x+\dfrac{8}{3}\ \ \ |\cdot3\\\\3y=-4x+8\ \ \ |+4x\\\\4x+3y=8

The slope-intercept form: y=-\dfrac{4}{3}x+\dfrac{8}{3}

The standard form: 4x+3y=8

Describe a scenario for 1/2 ÷ 3
Sholpan [36]
You can think of it as two separate fractions. 1/2 divided by 3/1. You can solve this by multiplying the first fraction by the reciprocal of the second fraction. A reciprocal is switching the fraction by turning it over. So you just have to solve 1/2 multiplied by 1/3. As a result you get 1/6 as the answer! Hope this helped!
