Question

Y+3=-3(×+2) Point slope form equation when graphed

Answer 1

The slope m = -3, and the point is (0,-9).

Step-by-step explanation:

The equation of a line in  slope-intercept form  is given as

                             y = mx + b

where m represents the slope and

           b represents the y-intercept.

⇒   y  +  3  =  −  3( x + 2)

subtract 3 from both sides.

⇒  y  =  - 3 x - 9

⇒ m  =  - 3 and the b  = - 9

Hence slope is -3 and y-intercept is -9

y-intercept = - 9 which is the coordinate point (0 ,-9)

To obtain any coordinate point on the line, select values for x and substitute them into the equation for corresponding value of y.

x  = -2 ⇒  y  =  -3 $\times$ -2 - 9

y = 6 - 9 = -3

 Hence the another point on the line is (-2,-3)
