Question

Find the equation of the line which has gradient 4 and goes through the point (3, 7)​

Answer 1

Answer:

• y = 4x - 5

Step-by-step explanation:

The gradient is the same term as the slope.

We have the line with the slope of 4 and passing through the point (3, 7).

Use the point - slope form and substitute the coordinates to get:

• y - 7 = 4(x - 3)
• y - 7 = 4x - 12
• y = 4x - 12 + 7
• y = 4x - 5
