Use the given conditions to write an equation for the line i

Use the given conditions to write an equation for the line in point-slope form and slope-intercept form. slope= -3 passing through (-5,-7)

Type the point-slope form of the line. (Simplify your answer. Use integers or fractions for any numbers in the equation.)

Type the slope-intercept form of the line. (Simplify your answer. Use integers or fractions for any numbers in the equation.)

Solution:
Point slope intercept form
= y y(1) = m( x x(1) ) m is the slope of the line and y(1),y(2) are the given points of line.

= (y+7) = -3(x+5)
= y+7 = -3x-15
= 3x+y+22=0

Slope intercept form
y = mx + b
y= -3x-7 (b is y intercept)(m is slope)
