Question

Please help me....Could you answer these 2 questions correctly?

Answer 1

#1 - First option: y + 7 =
`(-1)/(4)`(x -4)

#2 - First option: y = 2x - 5

Explanation:

#1

Given: (x1,y1) = (4,-7) and m =
`(-1)/(4)`;

To find the point slope form which is

y - y1 = m(x - x1); substitute (x1,y1) and m

y - (-7) =
`(-1)/(4)`(x -4)

y + 7 =
`(-1)/(4)`(x -4)

#2

Given: points (x1,y1) = (0, -5) and (x2,y2)=(4,3)

To find the slope we use

m =
`((y2-y1))/((x2-x1))` =
`((3-(-5)))/((4-0))` =
`(8)/(4)` = 2

Now pick a number to find b

y = mx + b

y1 = mx1 + b

-5 = 2(0) + b

b = -5

now plug into y = mx + b; which is

y = 2x - 5

Answer 2

A
