What is the equation of the line if slope is -2 and y-int is 9

Mathematics
1 answer:
AlladinOne [14]4 years ago
5 0

Answer:

y = -2x + 9

Step-by-step explanation:

Let's start from the -2x, the slope is -2. The x is basically what says, this is the slope. The plus nine is the y-intercept. If you think in graph terms (which is how you solve this problem) you will see that on the y-axis the line will intercept at the 9. The every x integer it goes down it goes that times two. For example, if you go sideways 1 spot, the line will be at y=11.
