Math Problem Statement

Find the slope and y intercept of the line y=7/4x-4

Solution

The given equation of the line is:

y=74x4y = \frac{7}{4}x - 4

This is in slope-intercept form, y=mx+by = mx + b, where:

  • mm is the slope
  • bb is the y-intercept

Slope:

The coefficient of xx is the slope, so: m=74m = \frac{7}{4}

Y-intercept:

The constant term is the y-intercept, so: b=4b = -4

Final Answer:

  • Slope (m): 74\frac{7}{4}
  • Y-intercept (b): 4-4

  1. What is the equation of a line with a slope of 74\frac{7}{4} and y-intercept of 55?
  2. How would you find the slope of a line if given two points on the line?
  3. What is the x-intercept of the line y=74x4y = \frac{7}{4}x - 4?
  4. How do you determine if two lines are parallel or perpendicular based on their slopes?
  5. How would the graph of y=74x4y = \frac{7}{4}x - 4 change if the slope were negative?

Tip: In the slope-intercept form, the slope tells you how steep the line is, and the y-intercept is where the line crosses the y-axis.
