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

so

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]

9514 1404 393

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
