Question 1203835: Write the equation of the line that passes through the point (6,-8) and has a slope 4. Found 3 solutions by math_tutor2020, MathLover1, kiks:Answer by math_tutor2020(3817) (Show Source):
y - y1 = m(x - x1) ...... point slope form
y - (-8) = 4(x - 6)
y + 8 = 4x - 24
y = 4x - 24 - 8
y = 4x - 32 is the final answer (in slope-intercept form anyway).
Check:
Plug in x = 6 and we should arrive at y = -8
y = 4x - 32
y = 4*6 - 32
y = 24 - 32
y = -8
We have shown the point (6,-8) is on the line y = 4x-32.
Everything checks out.
You can put this solution on YOUR website!
the equation of the line that passes through the point (,) and has a slope
use point slope formula
substitute given data
You can put this solution on YOUR website! Using the point gradient formula: y-y1=m(x-x1)
Sub the gradient into 'm; and the points into 'y1' and 'x1'.
hence
y+8=4(x-6)
y+8=4x-24
y=4x-32
