Question

Write the standard form of the line that passes through the given points. Include your work in your final answer. Type your answer in the box provided to submit your solution. (7, -3) and (4, -8)

Answer 1

It must have the same slope as the given line, so

m = -A/B = -1/-2 = 1/2

So far, we have

y = mx + b = x/2 + b

Use the given point to find b.

4 = -2/2 + b = -1 + b

b = 5

y = x/2 + 5

Multiply through by 2.

2y = x + 10

Standard form:

x - 2y = -10
