What is the equation of the line whose y-intercept is 3 and slope is 1?
1 answer:
Answer:
B. y = x + 3
Step-by-step explanation:
Let m represent the slope of the line.
Let c represent the y-intercept of the line.
Then the equation of the line with slope m and y-intercept c is given by
In this case, the value of m is 1 and the value of c is 3.
Substituting the given values in the equation:
Among the given options, option B represents the correct equation of the line.

Answer:
y = -4x.
Step-by-step explanation:
Begin by finding the slope of the line using the slope formula:
Plug in two points on the graph. We can use the points (-1, 4) and (0, 0):
Simplify:
m = -4.
Therefore, the equation of this line in slope-intercept form (y = mx + b) is:
y = -4x.
