3x−y=4
3 x minus y equals 4
y=−3x−4
y equals negative 3 x minus 4
y=3x+4
y equals 3 x plus 4
y=3x−4
y equals 3 x minus 4
From the graph, we can see that the line passes through the point (0, -4) and (1, -1).
To find the slope of the line, we use the formula:
m = (y2 - y1) / (x2 - x1)
m = (-1 - (-4)) / (1 - 0)
m = (-1 + 4) / (1 - 0)
m = 3/1
m = 3
Now, we have the slope (m) and a point (0, -4), we can use the slope-intercept form of the equation of a line:
y = mx + b
Substituting the known values:
-4 = 3(0) + b
-4 = 0 + b
b = -4
Therefore, the equation of the line in slope-intercept form is:
y = 3x - 4
Write the equation of the line in slope-intercept form.

y=5x+1
y equals 5 x plus 1
y=−5x−1
y equals negative 5 x minus 1
y=−5x+1
y equals negative 5 x plus 1
−5x−y=−1
To write the equation of the line in slope-intercept form, we need to solve for y.
The given equation is -5x - y = -1.
To isolate y, we will subtract -5x from both sides of the equation:
-y = 5x - 1.
Now, to solve for y, we can multiply both sides of the equation by -1, which will flip the sign:
y = -5x + 1.
Therefore, the equation of the line in slope-intercept form is:
y = -5x + 1.
Is this the correct graph of y=−13x+4?(1 point)
Responses
Yes, it is the correct graph because this graph has a y-intercept of (0,4).
Yes, it is the correct graph because this graph has a y -intercept of left parenthesis 0 comma 4 right parenthesis .
No, it is not the correct graph because this graph has a positive slope.
No, it is not the correct graph because this graph has a positive slope.
Yes, it is the correct graph because this graph has a y-intercept of (0,3).
Yes, it is the correct graph because this graph has a y -intercept of left parenthesis 0 comma 3 right parenthesis .
No, it is not the correct graph because this graph used (0,3) as the y-intercept.
No, it is not the correct graph because this graph has a positive slope. The equation y = -13x + 4 has a negative slope, indicating a downward-sloping line.
