Question

Write the slope-intercept form of the equation of the line parallel to y = 5x + 2 which passes through the point (4, 9).

Answer 1

what do you think will be the slope of line that is parallel to y = 5x + 2?

Answer 2

5?

Answer 3

correct.

Answer 4

ok, now we are also told that it passes through (4,9)

Answer 5

and we know the equation of a line can also be written as:
(y-y1) = m(x-x1)

where m is the slope of the line, and (x1, y1) is a point through which it passes

Answer 6

do you think you can now work out the equation of the line?

Answer 7

do you understand?

Answer 8

y = 5x - 11

Answer 9

perfect - well done!
