Math Problem Statement
Graph the line 5x - 2y = -10 using intercepts.
Solution
The equation provided in the image is:
To graph this line using intercepts, we will find the x-intercept and the y-intercept.
Step 1: Find the x-intercept
To find the x-intercept, set and solve for :
So, the x-intercept is .
Step 2: Find the y-intercept
To find the y-intercept, set and solve for :
So, the y-intercept is .
Step 3: Plot the intercepts and draw the line
- Plot the point on the x-axis.
- Plot the point on the y-axis.
- Draw a straight line through these two points to graph the equation.
Would you like a detailed drawing of the graph? Also, here are some questions to extend your understanding:
- What happens if we multiply both sides of the equation by a constant?
- How do you determine the slope from the equation ?
- What is the slope of the line from the two intercepts?
- Can you write this equation in slope-intercept form?
- How would you graph the line if given only the slope and a point?
Tip: Always check for both intercepts (x and y) to quickly graph a linear equation!
