Answer:
y = -1/2x - 3
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
Step 1: Determine known variables
Slope = -1/2 (m = -1/2)
y-intercept - (0, -3), so b = -3
Step 2: Write in known variables
y = -1/2x - 3
Ok so:
90 + 6x - 7.5x < 30
6x - 7.5x = -1.5
90 - 1.5x < 30
-90 -90
-1.5x < -60
-60/-1.5
x=40
40 < 30
Answer: The slope of line with a rise of 1 and a run of 2 is 1/2
The slope is rise over run
3/5
