1. Answer (assuming it can be in slope-intercept form):

Step-by-step explanation:

1) First, find the slope of the line between the two points by using the slope formula, . Substitute the x and y values of the given points into the formula and solve:

Thus, the slope of the line is .

2) Next, use the point-slope formula to write the equation of the line in point-slope form. Substitute values for , , and in the formula.

Since represents the slope, substitute in its place. Since and represent the x and y values of one point the line intersects, choose any of the given points (it doesn’t matter which one, it will equal the same thing) and substitute its x and y values into the formula as well. (I chose (-2,0), as seen below.) Then, isolate y and expand the right side in the resulting equation to find the equation of the line in slope-intercept form:
