Masteriza [31]

${x}^{2} = 11x \\ {x}^{2} - 11x = 0 \\ x(x - 11) = 0$

Product is equal to 0 when one of multipliers is equal to 0, so

$x = 0$

$x - 11 = 0 \\ x = 11$

What is the function rule for the line?

Salsk061 [2.6K]

Answer:

y =2/3x -2

Step-by-step explanation:

The y intercept is -2

The slope is

m = (y2-y1)/ (x2-x1)

Using the points (0,-2) and (3,0)

m = ( 0 - -2)/(3 -0)

= (0+2)/(3-0)

= 2/3

The slope intercept form is

y = mx+b where m is the slope and b is the y intercept

y =2/3x -2
