Answer

Step 4: Substitute the values of m and b into the slope-intercept form equation. We get y = 3x - 10.

Steps

Step 1 ：Step 1: Identify the slope (m) and the coordinates of the point (x1, y1). In this case, m=3, x1=4, and y1=2.

Step 2 ：Step 2: Substitute the values into the slope-intercept form equation, y = mx + b. We have 2 = 3*4 + b.

Step 3 ：Step 3: Solve for b. We get -10 = b.

Step 4 ：Step 4: Substitute the values of m and b into the slope-intercept form equation. We get y = 3x - 10.
