Write the equation of the line in fully simplified slope-intercept form
DochEvi [55]

Answer:

y = 3x - 7

Step-by-step explanation:

Slope - Intercept Form :  y = mx+b

m = slope

b = y - intercept

Slope =  \frac{rise}{run}

          = \frac3{1}

          = 3

So far:   y = 3x + b

Plug in a point from the graph, ex. (3,2)

2 = 3(3) + b\\\\2 = 9 + b\\\\b = -7

Equation :   y = 3x - 7

The 18th term of an arithmetic sequence is 49 and the first term is 15.
Tju [1.3M]

Answer:

33

Step-by-step explanation:

49-15=34

34/17=2

For this sequence, you can write this function:

f(x)=15+2(x-1)

Check:

f(18)=15+2(18-1)

f(18)=15+2(17)

f(18)=15+34

f(18)=49

So:

f(10)=15+2(10-1)

f(10)=15+2(9)

f(10)=15+18

f(10)=33
