Answer:

Pretty sure it's negative 3, cause then X would become -3X. Then when you would add 3X to both sides, it would cancel out both of the -3X then you would be left with 5 = 7, which we all know is not right.

Write in slope intercept form of the equation of a line passing through (-1,4) and perpendicular to y=x-5.

andrew11 [14]

Answer:

y=-x+3

Step-by-step explanation:

The general slope-intercept equation of a line is y=mx+b where m is the slope and b represents the y intercept. y and x are simply a point the line passes through. In this case, y=x-5, meaning m=1 and b=-5.

In order to find the perpendicular slope, we should take the current slope's <u>negative reciprocal</u>. We have:

$-\frac{1}{1} =\\-1$
