Answer:
The equations in the slope-intercept form
y = - 2 x + 5
y = - 2 x + 3
Step-by-step explanation:
The slope-intercept form of the linear equation is y = m x + b, where
- m is the slope of the line.
- b is the y-intercept.
To put any equation in the slope-intercept form state y on the left side, x and the numerical term on the right side, the coefficient of y must be 1.
Let us do that with the given equations
∵ 2x + y = 5
→ Subtract 2x from both sides to move x to the right sides
∴ 2x - 2x + y = 5 - 2x
∴ y = 5 - 2x
→ Switch 5 and - 2x
∴ y = - 2x + 5
∵ 3y = 9 - 6x
→ Divide each term by 3 to make the coefficient of y = 1
∴ [tex]\frac{3y}{3}=\frac{9}{3}-\frac{6x}{3}[/tex]
∴ y = 3 - 2x
→ Switch 3 and - 2x
∴ y = - 2x + 3
The equations in the slope-intercept form
y = - 2x + 5
y = - 2x + 3
Answer:
Write each equation in slope-intercept form.
y = -2x + 5
y = -2x + 3
What do the equations have in common? How are they different?
- The slopes are the same.
- The y-intercepts are different.
The system represents lines that (are parallel),
therefore the system has no solution.
