Hi,

Write an equation in slope-intercept form

line through point P(–10, 1) with slope –5

the standard point-slope form for an equation of a line y = mx + b  

where m is the slope and b the y-intercept.

y = -5x + b  Using ordered pair Pt(-10,1) to solve for b

1 = -5*-10 + b

-49 = b

y = -5x -49

 B & C are not in slope-intercept form.

------------

Sub -10 for x and see if y = 1 in A and D

A:  y = -5*(-10) - 49

y = 50 - 49 = 1

A works.

----------

D: y = -5x + 1 = -5*(-10) + 1

y = 51 not even close

---------

A is it.
