Question

Write the equation of the line with x-intercept 3 and passing through the point (5, 4)

Answer 1

Answer:

y=2x-6

Step-by-step explanation:

The line has an x-intercept of (3,0) and crosses through the point (5,4). Using these points, we can find the slope using the slope formula.

$m=\frac{y_2-y_1}{x_2-x_1}= \frac{4-0}{5-3} =\frac{4}{2}=2$

To write the equation of the line, substitute m=2 and the point (5,4) into the $y-y_1 = m(x-x_1)$.

$y-4=2(x-5)\\y-4=2x-10\\y=2x-6$

Answer 2

Answer:  The required equation of the line is $y=2x-6.$

Step-by-step explanation:  We are give to write the equation of a straight line with x-intercept 3 and passing through the point (5, 4).

Since the given line has x-intercept 3, so it will pass through the point (3, 0).

The slope of a line passing through the points (a, b) and (c, d) is given by

$m=\dfrac{d-b}{c-a}.$

Since the given line passes through the points (3, 0) and (5, 4), so its slope will be

$m=\dfrac{4-0}{5-3}=\dfrac{4}{2}=2.$

Therefore, the equation of the line is given by

$y-0=m(x-3)\\\\\Rightarrow y=2(x-3)\\\\\Rightarrow y=2x-6.$

Thus, the required equation of the line is $y=2x-6.$
