A system has two linear equations in two variables. The graphs of the equations have the same slope but different y-intercepts.

lesya [120]

<span>A system has two linear equations in two variables. The graphs of the equations have the same slope but different y-intercepts. How many solutions does the system have?
</span><span>
A. 0</span>

They have no solutions because these two lines are parallel. They have the same slope. However, two parallel lines have no solutions because they never intersect.

Hope this helps.

Write the equation of the line that is perpendicular to 3x + 7y = 15 and passes through (4, 9)

k0ka [10]

Answer:

7x - 3y = 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 3x + 7y = 15 into this form

Subtract 3x from both sides

7y = - 3x + 15 ( divide all terms by 7 )

y = - $\frac{3}{7}$ x + $\frac{15}{7}$ ← in slope- intercept form

with slope m = - $\frac{3}{7}$

Given a line with slope m the the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{-\frac{3}{7} }$ = $\frac{7}{3}$ , thus

y = $\frac{7}{3}$ x + c ← is the partial equation of the line

To find c substitute (4, 9) into the partial equation

9 = $\frac{28}{3}$ + c ⇒ c - $\frac{1}{3}$

y = $\frac{7}{3}$ x - $\frac{1}{3}$ ← in slope- intercept form

Multiply through by 3

3y = 7x - 1 ( subtract 3y from both sides )

0 = 7x - 3y - 1 ( add 1 to both sides )

1 = 7x - 3y, that is

7x - 3y = 1 ← in standard form
