To find the equation of a line given a slope and a point, we can use the point-slope form of a linear equation, which is:
y – y1 = m(x – x1)
Where:
- m is the slope of the line.
- (x1, y1) is the point through which the line passes.
In this case, we are given a slope m = 7 and a point (3, 4). Plugging these values into the point-slope formula:
y – 4 = 7(x – 3)
Next, simplify this equation:
y – 4 = 7x – 21
Now, add 4 to both sides:
y = 7x – 21 + 4
y = 7x – 17
So, the equation of the line with a slope of 7 that passes through the point (3, 4) is:
y = 7x – 17
