Answer (assuming it can be in slope-intercept form):Step-by-step explanation:1) First, find the slope of the line. Use the slope formula, . Substitute the x and y values of the given points into the formula and solve:

So, the slope is 2.

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

Since represents the slope, substitute 2 in its place. Since and represent the x and y values of a point the line intersects, choose one of the given points (it doesn’t matter which one, the results will equal the same thing) and substitute its x and y values into the formula as well. (I chose (1,2), as seen below.) Then, isolate y to put the equation in slope-intercept form ( format) and find the following answer:
