Answer y = 7/9x + 3 5/9 is the equation of the line that passes through the two points given

Step by step

We are given a line crossing through points

(34, 30) and (25, 23)

We can find slope using formula
y2 - y1 over x2 - x1

23 - 30 over 25 - 34

-7 over -9 or 7/9 slope

Now use point slope formula to find y intercept

y - y1 = m ( x - x1)

y - 30 = 7/9 (x - 34)

y - 30 = 7/9x - 238/9

*238/9 simplifies to 26 4/9

Add 30 to both sides to isolate y

y -30 +30 = 7/9x - 26 4/9 + 30
Simplify

y = 7/9x + 3 5/9

This is the equation of the line
