10c^2-60cd +80d^2

(2c - 8d) (5c -10d)

this  \\ is \\ because...

2c*5c=10c^2

2c * -10d=-20cd \\ -8d*5c=-40cd \\ -20cd-40cd=-60cd

-8d * -10d = 80d

(3,4) and (0, 5)<br> write a linear equation
Nina [5.8K]

Answer:

y=-1/3x+5

Step-by-step explanation:

<u>Slope-intercept form</u>

y=mx+b

m => slope

b => y-intercept

<u>Slope</u>

m=(y2-y1)/(x2-x1)=(5-4)/(0-3)=1/(-3)=-1/3

<u>Y-intercept</u>

y=-1/3x+b

5=-1/3(0)+b

5=b

<u>Final equation</u>

y=-1/3x+5
