Answer:
y=-2.5+6
Step-by-step explanation:
First, you have to calculate the slope. First, you must find the rate at which the x and y values increase. The x is increasing by 1 each time, and the y is increasing by -2.5. The slope is equal to y/x, which in this case is equal to -2.5/1, which is just -2.5, so that's the slope. Now we need the y-intercept, which is the value of y when x=0. The y-intercept is luckily given to you right on the table, and is 6. So our equation is y=-2.5x+6. Remember the negative! :)
