The correct answer will be 4x^{2} - 32x + 28

Let's simplify step-by-step.

(x−7)(−9)+(x−7)(4x+5)

Distribute:

= (x)(−9)+(−7)(−9)+(x)(4x)+(x)(5)+(−7)(4x)+(−7)(5)

= −9x+63+4x2+5x+−28x+−35

Combine Like Terms:

= −9x+63+4x2+5x+−28x+−35

= (4x2)+(−9x+5x+−28x)+(63+−35)

= 4x2+−32x+28

Write an equation in point-slope form and slope-intercept form for each line.
Kobotan [32]

A: Slope-intercept form: y = 2 x − 1 Point-slope form: y − 7 = 2 ⋅ ( x − 4 )

B: Slope-intercept form: y = 4 x + 7 Point-slope form: y + 1 = 4 ⋅ ( x + 2 )

C: Slope-intercept form: y = 1/2 x − 8 Point-slope form: y + 4 = 1/2 ⋅ ( x − 8 )
