Y-intercept, where the graph crosses y-axiss is 0. that means in the equation: y = mx + b
b = 0
the m, is slope. looking at the graph you can see the points on the line are connect up 4 right 1. rise/run = slope = 4
y = 4x
2x+5=27
subtract 5 from both sides:
2x=22
divide by 2 on both sides:
x=11
Hmmm unless you can do negatives, I'd say 10 and 0. 10 minus 0 is 10 (which fits) and the product of 10 and zero IS zero. does that make sense?
8 percent of 20
=0.08 x 20
=1.6
Answer:

Step-by-step explanation:
x²+20x-12=0
a = 1, b = 20, c = -12
