Derive the equation of the line in slope-intercept form.
(0,4) (1,8)
To find the equation of the line in slope-intercept form, we need to use the formula:
y = mx + b
where m is the slope of the line and b is the y-intercept.
First, let's find the slope (m) of the line using the given points (0,4) and (1,8).
m = (y2 - y1) / (x2 - x1)
Substituting the coordinates (x1, y1) = (0,4) and (x2, y2) = (1,8):
m = (8 - 4) / (1 - 0)
m = 4 / 1
m = 4
Now that we have the slope, we can substitute it into the equation to find the value of b.
Using the slope-intercept form, and substituting the point (1,8):
8 = 4(1) + b
8 = 4 + b
Subtracting 4 from both sides:
8 - 4 = b
4 = b
Now we have the value of b.
The equation of the line in slope-intercept form is:
y = 4x + 4
Write the equation of the line in slope-intercept form.
(1,-1) (0,2)
To find the equation of the line in slope-intercept form, we will use the formula:
y = mx + b
where m is the slope of the line and b is the y-intercept.
First, let's find the slope (m) of the line using the given points (1,-1) and (0,2).
m = (y2 - y1)/(x2 - x1)
Plugging in the coordinates (x1, y1) = (1,-1) and (x2, y2) = (0,2):
m = (2 - (-1))/(0 - 1)
m = 3/(-1)
m = -3
Now that we have the slope, we can substitute it into the equation to determine the value of b.
Using the slope-intercept form and substituting the point (1,-1):
-1 = -3(1) + b
-1 = -3 + b
Adding 3 to both sides:
2 = b
Now we have the value of b.
The equation of the line in slope-intercept form is:
y = -3x + 2
Write the equation of the line in slope-intercept form.
(0,-2) (3,0)
To find the equation of the line in slope-intercept form, we will use the formula:
y = mx + b
where m is the slope of the line and b is the y-intercept.
First, let's find the slope (m) of the line using the given points (0,-2) and (3,0).
m = (y2 - y1) / (x2 - x1)
Plugging in the coordinates (x1, y1) = (0,-2) and (x2, y2) = (3,0):
m = (0 - (-2)) / (3 - 0)
m = 2 / 3
Now that we have the slope, we can substitute it into the equation to determine the value of b.
Using the slope-intercept form and substituting the point (3,0):
0 = (2/3)(3) + b
0 = 2 + b
Subtracting 2 from both sides:
-2 = b
Now we have the value of b.
