Question 511551: I don't know how to calculate the slope, x-intercept, and y-intercept, and list this information. I also need to label the two points used to draw on the graph.
1)y = x + 3
2)y = -2x - 7
3)2x + 3y = 9
Answer by oberobic(2304)   (Show Source):
You can put this solution on YOUR website! y = mx + b is the template for the slope-intercept
m = slope
b = y-intercept, which is the point (0,b)
The x-intercept is the point where y=0, which is (x,0).
.
1) y = x + 3
.
slope = 1
y-intercept = (0,3)
x-intercept = (=3,0)
With these two points, you can draw a line.
.
2) y = -2x-7
.
slope = -2
y-intercept = (0,-7)
x-intercept = (-7/2,0)
.
3) 2x + 3y = 9
.
3y = -2x +9
y = -2/3x + 3
.
slope = -2/3
y-intercept = (0,3)
x-intercept = (9/2, 0)
.
.
Done.
