Determine the equation of the line with slope 3/4 passing through the point 4,0

Vitek1552 [10]

Answer:

$y = \frac{3}{4}x - 3$

Step-by-step explanation:

If it has a slope of 3/4, then it will look like this:

$y = \frac{3}{4}x + b$

If it passes through (4, 0), than y = 0 when x = 4

$y = \frac{3}{4}(4) + b$

$y = 3 + b$

$b = -3$

Therefore, the equation is $y = \frac{3}{4}x - 3$ .
