Question

write the slope-intersept form of the equation of the line passing through the point(-5, 1) and perpendicular to the line y=4/3x=4

Answer 1

We know that the equation has to be perpendicular, meaning the slope is the negative reciprocal: 4/3---->-3/4
And they give you the points (-5, 1)
Now just plug this info into the point-slope formula:
y-y1=m(x-x1)

Answer 2

what is the y1

Answer 3

(x1, y1)----> (-5, 1)

Answer 4

then wht is y and x

Answer 5

they're just variables like in:
y=mx+b

Answer 6

im so confused
