Answer:
A - y= 4x -6
Explanation:
Slope-intercept form helps describe the graph of a linear function.
Slope
Slope-intercept form is written as y = mx + b, where m is the slope and b is the y-intercept.
Slope is rise over run. This means that slope equals the change in y divided by the change in x. We can find the slope of a graph by counting the changes in y and x between 2 points. For example, we can use the points (1,-2) and (2,2). The y-value increases by 4 and the x-value increases by 1. This means that the slope is 4/1, which can be simplified to 4. So, m = 4.
Y-intercept
The y-intercept is where the line intersects with the y-axis. Remember that the y-axis is the vertical axis. The y-intercept is also always when x = 0. The graph crosses the y-axis at (0,-6). This means that the y-intercept is -6. So, b = -6.
Writing the Equation
Now, all we need to do is plug the values into y = mx + b. The final equation is y = 4x - 6.
