What is the slope intercept equation for the line below?

y=5/4x-4 or y=1.33x-4

Step-by-step explanation:

to find the slope intercept form of a line, take the two points and find the slope. it is rise over run, so count the amount the line rises and then goes over before intersecting another unit. in this case, the line goes up 5 and over 4 before reaching the other point on the graph.

to find the value for b, invert the y and x values of a point into the equation y=mx+b, then solve it as if it were an equation. like this, if I were to choose the lower point.

y=mx+b

-4=(5/4)0+b

-4=0+b

-4=b

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.
