Point-Slope Form<br> *See photo*
Ne4ueva [31]

Answer:

y = 3x - 5

Step-by-step explanation:

We know that the equation 'y = 3x + ?' intersects the point (1, -2). This means that when x = 1, y = -2 in out equation above. To solve this just plug in the x and y values to get '?'.

y = 3x + ?\\-2 = 3(1) + ?\\-5 = ?

Now that we know '?' is -5, we write it back into slope intercept form, so our final answer is y = 3x - 5
