Answer:

I'm assuming it's asking for the equation of the line

y = 2x - 1

Explanation:

Step 1: Use the formula y = mx + b to solve

This is slope-intercept form of a line. We are given the slope of 2 in the question, and a point (x, y), which is (4, 7). Plug those values into the equation above and solve for b (the only variable we are missing

7 = 2(4) + b

7 = 8 + b

-1 = b

Step 2: Rewrite the formula using the slope and the b value we just calculated

y = 2x - 1
