Answer:
B. y = 5/2x - 14
Step-by-step explanation:
Find the slope of the original line and use the point-slope formula y − y 1 = m (x − x 1 ) to find the line parallel to y = 5 /2 x − 10 .
y = 5 /2 x − 14 PARALLEL
...................................................................................................................................................
Find the negative reciprocal of the slope of the original line and use the point-slope formula y − y 1 = m ( x − x 1 ) to find the line perpendicular to y = 5 /2 x − 10 .
y = − 2 /5 x − 157 /5 PERPENDICULAR
Hello,
Thanks
Hello from MrBillDoesMath!
Answer: f(x) = (2/3)*x -3 -- which is not a provided answer..
Discussion:
We are given that y + 7 = (2/3) * (x + 6). Multiply out the right hand side:
y + 7 = (2/3) * x + (2/3) * 6 = (2/3) *x + 12/3
= (2/3)*x + 4
Subtract 7 from both sides:
y + 7 - 7 = (2/3)*x + 4 - 7
or
y = (2/3)*x -3
Thank you,
MrB
y + 7= 2/3(x+6)
