Given a graph of a line, we can write a linear function in the form y=mx+b by identifying the slope (m) and y-intercept (b) in the graph.

And put a horizontal line through it this is the graph forMoreSo if we go to 3 on the y-axis. Here 1 2. And put a horizontal line through it this is the graph for y equals. Three put some arrows show that it goes to infinity. That's our graph.

Plus 2 that is telling us to findMoreBut that's all it is so the rule is that we've got y equals 3x. Plus 2 that is telling us to find the y coordinate. We do 3 lots of the x-coordinate. And then we add 2. So if the x-coordinate.

1 Answer. The slope is zero. This is a perfectly horizontal line passing through y=?3 . It is neither increasing nor decreasing so its slope must be zero.

To graph an equation using the slope and y-intercept, 1) Write the equation in the form y = mx + b to find the slope m and the y-intercept (0, b). 2) Next, plot the y-intercept. 3) From the y-intercept, move up or down and left or right, depending on whether the slope is positive or negative.

How to Graph y = -2 using the Slope and y-intercept - YouTube YouTube Start of suggested clip End of suggested clip Let's think of our slope as 0. Over 1 so we can look at the rise over run on the graph. Okay soMoreLet's think of our slope as 0. Over 1 so we can look at the rise over run on the graph. Okay so here's the x-axis or continuing to graph this.

So instead of writing 2x x is nowMoreSo i'm going to replace x with negative 2 in the equation. So instead of writing 2x x is now negative 2. And when i simplify. This i'm going to get a negative 3..

How to Graph y=4 - YouTube YouTube Start of suggested clip End of suggested clip Line when we write out four. And there we have our graph. So it's horizontal. But what horizontalMoreLine when we write out four. And there we have our graph. So it's horizontal. But what horizontal line i will write out before i plus 4 and there's our graph. So let's recap we're given y equals 4.
