Transcript text: What are the x-intercept and y-intercept of the line $y=4 x+58$
a) x-intercept $(4,0)$
y-intercept $\left(0, \frac{4}{5}\right)$
b) $x$ intercept: $\left(-\frac{5}{4}, 0\right)$
$y$-intercept: $(0,5)$
c) $x$-intercept $(5,0)$
y-intercept $\left(0,-\frac{5}{4}\right)$
Solution
Solution Steps
To find the x-intercept and y-intercept of the line given by the equation \( y = 4x + 58 \):
X-intercept: Set \( y = 0 \) and solve for \( x \).
Y-intercept: Set \( x = 0 \) and solve for \( y \).
Step 1: Finding the X-Intercept
To find the x-intercept, we set \( y = 0 \) in the equation \( y = 4x + 58 \):
\[
0 = 4x + 58
\]
Solving for \( x \):
\[
4x = -58 \implies x = -\frac{58}{4} = -14.5
\]
Thus, the x-intercept is \( (-14.5, 0) \).
Step 2: Finding the Y-Intercept
To find the y-intercept, we set \( x = 0 \) in the equation \( y = 4x + 58 \):
\[
y = 4(0) + 58 = 58
\]
Thus, the y-intercept is \( (0, 58) \).
Final Answer
The x-intercept is \( (-14.5, 0) \) and the y-intercept is \( (0, 58) \).
