Transcript text: Write an equation of the line passing through $(-3,1)$ and $(4,2)$. Give the answer in standard form.
Solution
Solution Steps
Step 1: Calculate the slope (m)
The slope of the line, \(m\), is calculated using the formula \(m = \frac{y_2 - y_1}{x_2 - x_1}\), which gives \(m = \frac{2 - 1}{4 + 3} = 0.14\).
Step 2: Find the y-intercept (b)
Using the point-slope form \(y - y_1 = m(x - x_1)\) and substituting \(m = 0.14\) and the point \((-3, 1)\), we solve for \(b\) to get \(b = 1 - (0.14)(-3) = 1.43\).
Step 3: Convert to standard form (Ax + By = C)
To convert the slope-intercept form \(y = 0.14x + 1.43\) to standard form, we rearrange it to get \(0.14x - y = -1.43\).
Final Answer:
The equation of the line in standard form is \(0.14x - y = -1.43\).
