y = 7

Simplifying numerators/ denominators

\frac{1+3}{-1+3} = \frac{y-1}{2+1}

\frac{4}{2} = \frac{y-1}{3}

2 = \frac{y-1}{3} (cross- multiply )

y - 1 = 6 ( add 1 to both sides )

y = 7

Find the equation of the line passing through the points (5,21) and (-5,-29)
Assoli18 [71]

Answer:

Look below

Step-by-step explanation:

lets have -29 be y2 and -5 be x2

21 - (-)29

5 - (-)5

Subtracting a negative is just adding it so

21 + 29   50
5 + 5       10

50/10

this simplified, is 5/1 or 5

y=5x+b

now we need to find b, so we substitute  y and y

x = 5

y = 21

21=5*5=b

5*5 is 25

now we need to get to 21


25 -4 is 21

b = -4

y=5x-4
