Question

Write the equation of the line given the slope and a point on the line. Type your answer in the box without skipping any spaces. m = 3, point (2, 1)

Answer 1

given the gradient m , and a point (x1 , y1)

the equation of the line is:

y- y1 = m(x -x1)

Answer 2

wat is the question?

Answer 3

y-1 = 3(x -2)

Answer 4

Y=3X-5?

Answer 5

Using slope intercept form, y= mx + b and the fact that m = 3, we get
y = 3x + b.
Now use the specific point you're given to solve for b. Plugging in (2, 1) gives:
1 = 3(2) +b
b = 1-6 = -5
so m = 3, b = -5 and the equation of the line is
y = 3x - 5

Answer 6

Write the equation of the line given the slope and the y-intercept. Type your answer in the box without skipping any spaces. m = 2, y-intercept (0, -9)

I know this is the same thing but becuse it has a zero how would u go about solving this?

Answer 7

The y intercept is the point where the line crosses the y axis. Because it crosses the y axis, that means the x coordinate of that point will always be 0. The y coordinate of the point is the intercept, or the b in "y = mx + b"
