for the function rule y= -2x -3, provide the x-y coordinates of the y-intercept and the x-intercept. show your work

y-intercept means put zero for x and x-intercept means put zero for y so y -intercept gonna be :
y = -2(0) -3 ⇒ y = 0-3 =-3 so y-intercept is -3  or (0 , -3 )
x-intercept gonna be :
0 = -2x -3 ⇒ 3 = -2x ⇒ -3/2 = x ⇒ x = -1.5  so x-intercept is -1.5 or ( -1.5 , 0 ) :)))
i hope this be helpful

                               y = -2x - 3

--  The y-intercept is the point where the graph crosses
the y-axis.  But  x=0  everywhere on the y-axis, so

                               y = -2(0) - 3

                               y =         - 3 .

                                         0 = -2x - 3

Add 2x to each side:     2x  =         -3

Divide each side by 2:    x =          -3/2 .
