Question

Write in standard form an equation of the line passing through the given point with the given slope.

slope =-8: (1,-5)
a. -8x + y = 3
b. 8x + y = 3
c. 8x-y=3 d. 8x+y=-3​

Answer 1

Opt B.

Explanation:

Remember that the equation of a line tells us that y=mx+b, where m is the slope (Which we have and is -8), just need to find b, for that, lets eval the given point (1,-5) in the above equation.

-5=-8*1+b

Where we obtain that b=3

Our line is written as y=-8x+3

And in standard form that would be (grouping variables in the same side of equality sign)

y+8x=3
