Find the y-intercept and x-intercept
1) Find the x-intercept, substitute y = 0
0 = -x-5
5=-x
x= -5
Therefore, the x-intercept is at -5
2) Find the y-intercept, substitute x = 0
y= -0 - 5
y = 0 - 5
y = -5
Therefore, the y-intercept is at -5 too.
Plot the line graph from x = -5 to y = -5 and it should be like this.
Note - You can easily find the y-intercept just looking at "b value" from y = mx+b when m is the slope and b is the y-intercept.
Answer:
Step-by-step explanation:
1) since -5 is graphed in the equation we know the y-intercept is -5
2) since we already know the point (0,-5) form the y-intercept, we pick x-values and plug them into the equation. I'll use -4, 3, and 9
y=-x-5 y=-x-5 y=-x-5
y=-9-5 y=-3-5 y=--4-5
y=-14 y=-8 y=-1
3) we then plot the 4 points we found and draw a straight line connecting them, and then we put arrows on either side of the line because the question did not say that it was a line segment.
4) And check your work by going to Google and typing "student desmos graphing calculator" and typing in your equation.
