See a solution process below:

Explanation:

The equation in the problem is in slope-intercept form. The slope-intercept form of a linear equation is: #y = color(red)(m)x + color(blue)(b)#

Where #color(red)(m)# is the slope and #color(blue)(b)# is the y-intercept value.

#y = color(red)(-3)x + color(blue)(3)#

Therefore:

The slope for this line is: #color(red)(m = -3)#

The #y#-intercept for this line is: #color(blue)(b = 3)# or #(0, color(blue)(3))#

#"slope "=-3," y-intercept "=3#

Explanation:

#"the equation of a line in "color(blue)"point-slope form"# is.

#•color(white)(x)y=mx+b#

#"where m is the slope and b the y-intercept"#

#y=-3x+3" is in this form"#

#rArrm=-3" and y-intercept "=3#
graph{(y+3x-3)((x-0)^2+(y-3)^2-0.04)=0 [-10, 10, -5, 5]}
