HI;
Note: to determine the solpe , solve for y in order to put the equation of the line in the slope-intercept form y = mx + b where m is the slope and b is the y- intercept(the valueof y when the line passes thru the y-axis
.
3x - 3y = -9
x- y = -3
x + 3 = y
.
y = x + 3
slope = 1 or (1/1) positive slope tells us the line slopes to the right
.
(As y varies by 1, x varies in the same direction by 1!)
y-intercept is 3 (0,3) a point on the line
.
(0, 3) and (1,4) and (2, 5) are points on the line
