Question

Write the equation of a line with a slope of 2 and passing through the point (4, -5)?

Answer 1

Answer: Y=2x-13

you can use the point slope form to solve something like this or you can use desmos to help with graphing

Answer 2

y = 2x - 13

Explanation:

Slope intercept equation of a line

y = mx + b

m is the slope = 2

y = 2x + b

To find "b" plug in the given point (4, -5)

-5 = 2(4) + b

-5 = 8 + b

Subtract 8 from both sides

-13 = b

Using m = 2 and b = -13 the equation becomes

y = 2x - 13
