To find the corresponding y-values for each x-value for the function y = -2x + 5:
1. When x = -1:
y = -2(-1) + 5
y = 2 + 5
y = 7
2. When x = 0:
y = -2(0) + 5
y = 0 + 5
y = 5
3. When x = 1:
y = -2(1) + 5
y = -2 + 5
y = 3
4. When x = 2:
y = -2(2) + 5
y = -4 + 5
y = 1
So the completed table is:
x: -1, 0, 1, 2
y: 7, 5, 3, 1
Now let's plot these points on a graph.
x-axis from -3 to 3
y-axis from -5 to 8
The points to plot are (-1, 7), (0, 5), (1, 3), and (2, 1).
After plotting the points, connect them with a straight line.
The graph should show a line that passes through these points.
Complete the table for the function `y=-2x+5`and then plot the points on the grid.
x:−1 ,0 ,1 ,2
Y:?,?,?,?
