Answer:
The answer is b the slope is negative 2 and the y-intercept is (0,3)
Step-by-step explanation:
The y-intercept is simply the point of the line that is on the y-axis. And a point can only be on the y-axis if it's x coordinate is zero. So from the table you can tell that the y-intercept is (0,3)
To find the slope you use the equation Y=Mx+b. In the equation M represents the slope, b represents the y-intercept and x and y represent the x and y of a point on the line. First plug in the y-intercept into the equation. You will get 3 =m(0) + b. Which you can use to find out that b is 3. Now your equation is 3 = Mx + 3. Now you can put in another to solve it. let's do the point (2,-1). You plug in the x and Y to get the equation -1 = m(2) +3. Subtract 3 from both sides to get -4 =m(2). Then divide 2 from both sides to get m=-2. Therefore the slope is -2
