Given expression :

  • y = kx

let's plug the value of x as 0.4 and y as 20 in the given equation :

  • k = 20 ÷ 0.4

  • k = 50

correct choice - D. 50

\\ \sf\longmapsto y=kx

Write an equation in point-slope form of the line that passes through the point (−3,6) and has a slope of 5.
strojnjashka [21]

Answer:

Below in bold.

Step-by-step explanation:

Point slope form is y - y1 = m(x - x1)

where m = the slope of the line and (x1, y1) is a point on the line.

Here m = 5, x1 = -3 and y1 = 6.

So we have:

y - 6 = 5( x - (-3))

y - 6 = 5(x + 3)   (Answer)
