Question

Write an equation in point-slope form of the line that passes through (-2, -1) and has a slope of -3. Change the equation to slope-intercept form. Change the equation to standard form.

Answer 1

 

Hello:
equation is the line is : y = ax+b        a is a slope
 y = -3x+b
passing through the point (−2;−1) :   -1 =(-3)(-2)+b...b=-7
y = -3x-7

or : 3x+y= -7
