To find the Y-intercept, plug 0 in for X, so you have 0+Y=-3, or Y=-3. Therefore, your Y-intercept is at the point (0,-3). You do the same thing to find the X-intercept, only reversed. X+0=-3, so X=-3. This intercept is at (-3,0).
x+y=-3 Change to slope-intercept form y=-x-3y-intercept = -3 Plot point (0,-3)Slope = coefficent of x = -1 Slope = Rise/run = Y/X From 0,-3 move down -1 and to the right 1 Or move up one and to the...
all graphs of the form y=mx+c are simple to graph. SImpley notcice that it is a straight line, with gradiant m, and y-intercept of c.
So your example gives us a graph with a gradiant of -1 going...
Firstly, equate x to zero. This makes y = -2 when x = 0, so th co-ordinates of the y-intercept are (0,-2).
Next, for every increase/decrease in x of 1, increase/decrease y by 3. So the co-ordinates...
Function form this is X + 2Y = - 3 In slope/intercept form it is Y = - 1/2X - 3/2 To find the intercepts, set X to 0 and solve, then set y to 0 and solve. Y = -(1/2)(0) - 3/2 = -3/2 so the y...
