Question

A line passes through the points (-20, 16) and (10, 4). What is the equation of the line in standard form? (1 point)
2x + 5y = 8
y=-(2/5)x+8
2x + 5y = 40
X + 5y = 40

Answer 1

Slope = (4−16)/(10−(−20)) = −12/30 = −2/5.
y = (−2/5)x + b, plug (10,4): 4 = (−2/5)(10) + b → 4 = −4 + b → b = 8.
Standard form: 5y = −2x + 40 → 2x + 5y = 40.

Answer: 2x + 5y = 40.
