Chapter 2: Q24. (page 79)

Write an equation in slope-intercept form for the line that satisfies each set of conditions.
24. slope $0.25$ , passes through $(0, 4)$

Short Answer

Expert verified

The equation of the required straight line in slope-intercept form is $y = 0.25 x + 4$ .

Step by step solution

– State the concept

The slope intercept form of a straight-line equation is $y = m x + c$ where $m$ is the slope and $c$ is the y-intercept.

The equation of a straight-line having slope $m$ and passing through the point $(h, k)$ is given as $y - k = m (x - h)$ .

– List the given data

It is given that the slope of the line is $0.25$ and the line passes through $(0, 4)$ .

Then, $m = 0.25$ and $(h, k) = (0, 4)$ .

– Write the equation

Put $m = 0.25$ and $(h, k) = (0, 4)$ in $y - k = m (x - h)$ to get,

$y - 4 = 0.25 (x - 0)$

$y - 4 = 0.25 x$ (Simplify)

y - 4 + 4 = 0.25 x + 4

(Add 4 to both sides)

$y = 0.25 x + 4$ (Simplify)

So, the required equation of the straight line in slope-intercept form is $y = 0.25 x + 4$ .
