Line EF has an equation of a line y = −2x + 7. Which of the following could be an equation for a line that is perpendicular to l

yarga [219]

Answer:

$y=\frac{1}{2} x-3$

Step-by-step explanation:

Step 1

Find the slope of the line EF

we have

$y=-2x+7$

The slope of the line EF is equal to

$m=-2$

Step 2

Find the slope of the line perpendicular to the line EF

we know that

If two lines are perpendicular, then the product of its slopes is equal to minus one

$m1*m2=-1$

we have

$m1=-2$ -----> slope of the line EF

Find the value of m2

substitute

$(-2)*m2=-1$

$m2=1/2$

therefore

the equation $y=\frac{1}{2} x-3$ could be an equation for a line that is perpendicular to line EF

Write the equation of the line that is parallel to y=4x-1 and passes through the point (4.9)

lutik1710 [3]

Answer:

y = 4x -7

Step-by-step explanation:

Rearranging the slope-intercept for equation, we can find the intercept:

y = mx +b

y -mx = b . . . . . subtract mx

We know the slope of the parallel line is the same as that of the given line (m=4), so we only need to find 'b'.

b = 9 -4(4) = -7

The desired equation is ...

y = mx +b

y = 4x -7
