Graph a line represented by y=3x+4
Give some coordinate examples
To graph the line represented by y=3x+4, we can plot several coordinate examples. Here are a few:
1) When x = 0:
y = 3(0) + 4
y = 4
Coordinate example: (0, 4)
2) When x = 1:
y = 3(1) + 4
y = 7
Coordinate example: (1, 7)
3) When x = -1:
y = 3(-1) + 4
y = 1
Coordinate example: (-1, 1)
4) When x = 2:
y = 3(2) + 4
y = 10
Coordinate example: (2, 10)
Plotting these points on a coordinate grid and connecting them will result in a line with a slope of 3 passing through the y-intercept (0, 4).
