X^2-5x-6<br> X^2+3x-40<br> X^2+3x-4

luda_lava [24]

x² - 5x - 6

= x² + x - 6x - 6

= x(x + 1) - 6(x + 1)

= (x - 6) (x + 1)

x² + 3x - 40

= x² + 8x - 5x - 40

= x(x + 8) -5(x + 8)

= (x - 5) (x + 8)

x² + 3x - 4

= x² + 4x - x - 4

= x(x + 4) -1(x + 4)

= (x - 1) (x + 4)

Write the equation of the line in fully simplified slope intercept form

Naily [24]

Answer: y = (1/4)x - 1

Step-by-step explanation:

Slope intercept form is $y = mx + b$ . The $y$ -intercept is -1 so we have $y = mx - 1$ . To find $m$ , look at the points $(0, -1)$ and $(4, 0)$ . The line goes up 1 and over 4, so the slope, $m$ , equals $1/4$ . Thus the full equation is

$$y = (1/4)x - 1$ .
