A line with a slope of 4 passes through the point (2,-1) also passes through the point (x,0). What is the value of x?

Question

I need help with my homework right away! It's almost due!

Answer 1

Use definition of slope

(0 + 1) / (x - 2) = 4

Answer 2

slope = m = 4

through (2,-1), and (x,0)

what is the line's equation? what is x? about 2.41. what is slope? 4

4 = change in y over change in 4 = 1/(x-2)

4x -8 = 1

4x = 9

x = 2.25

line is: y = 4(x-2.25)

or y= 4x -9, in slope intercept form with y intercept = -9
