Step-by-step explanation:
Y=(x+1)(x-4)
this should be correct.
Answer:
Point-slope form: y + 3= -1(x + 4)
Slope-intercept form: y = -1x - 7
y = m * x + b,
where:
m is the slope; and
b is the intercept of the y-axis.
Answer:
2n + 2
Step-by-step explanation:
The formula for nth term of an arithmetic progression is 
In this example we have d = 2 (difference, +2 each time) and a1 =4 (first term of sequence).

The answer is 269. Hope this helped!! Could I possibly get brainliest!? :)
