What is the equation of the line passing through the points (2, -1) and (5.-10) in slope-intercept form
O y=-3x-5
O y=-3x+5
Oy - 3x-5
O y=3x+5

y = -3x + 5

Step-by-step explanation:

Usually by drawing a simple graph, you can tell what the equation is, even if the graph isn't 100% accurate. From the points alone, you can tell that the slope is negative, since as you increase in x you decrease in y (which is a negative relationship). You can tell that it's +5 rather than -5 because the graph sketched shows that the line goes above 0 (indicating a positive number), rather than below (a negative number).
