What is the equation of the line that passes through the point (4, 3) and has a slope
of 1?

y = x - 1

Step-by-step explanation:

Since we already know the slope, we need to find the y - intercept.

We plug in the x and y coordinates that we know and slope into the equation to find y intercept.

Once we know this, we can replace the b and m in the y = mx + b and that is the equation of the line.

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
