Answer:

y=-3x+4

Explanation:

Slope-intercept form is written as y=mx+b, where m is the slope and b is the y-intercept. Using the information given we can plug in the numbers to get the correct equation. This looks like y=-3x+4.

Slope-intercept form is helpful because we can use it to find coordinate points and graphs. By graphing the y-intercept and then using the slope to count out points, you can find the function. Additionally, by plugging in values for x or y, you can find coordinate pairs.
