Answer:
Step-by-step explanation:
1) First, find the slope by using the slope formula, . We can see that the two points marked on the line are (0, -3) and (3,0). So, substitute the x and y values of those points into the formula and solve:
So, the slope is 1.
2) Slope-intercept form is represented by the formula . Substitute values for and in order to write an equation.
Substitute 1 for since it represents the slope. Substitute -3 for since it represents the y-intercept. (Remember that the y-intercept is the point at which the line intersects the y-axis. So, by looking at the graph provided, we can see that (0,-3) is the y-intercept without doing any calculations.) This gives the following answer:
