1. It's in point-slope form right now
y - 7 = -x - 4
x + y = 3
2. Find the slope through (y2-y1) / (x2-x1)
The slope is 3.
Use the point slope formula: y - 9 = 3 (x - 8)
y - 9 = 3x - 24
y = 3x - 15
3. a. standard form
b. point-slope
c. slope-intercept
d. standard
5. Use point-slope: y - 8 = 6 (x - 3)
y - 8 = 6x - 18
-6x + y = -10
9 of his buttons are not red. 1/8 of 72 is 9
72×1/8=8
72÷8=9
Y = kx - <span>y varies directly as x in this function
</span> - y varies inversely as x in this function
For y varies directly as x
For y varies inversely as x
