Write the equation of the line that passes through (−1, 5) and has a slope of 3 in point-slope form. (2 points)
aleksandr82 [10.1K]
The point-slope form: y-y_0=m(x-x_0)

m = 3; (-1; 5) \to x_0=-1;\ y_0=5

subtitute

y - 5 = 3(x - (-1))

y - 5 = 3(x + 1)

2a. Determine the equation of the line connecting the points (0, -1) and (2, 3) *
Sauron [17]
First create the equation y=Mx+ B

B is the y intercept so when y = 0, B = -1.

Now we have y=Mx - 1

The slope is M. We can calculate this by using the formula M = (y2 -y1) / (x2 - x1)

Use the points (0, -1) and (2,3) for these values. So y2 = 3, y1 = -1, x2 = 2, x1 = 0

Plug them into the equation and solve

M = (3 + 1) / (2 - 0)
M = 4/2 = 2

Now we have the equation y = 2x - 1

Next to figure out if the points given are on the line you take the values and plug them into your equation like so: 4 = 2(-2) - 1

2(-2) - 1 does not equal 4 so this point does not fall on this line. Follow this same procedure for the next point given.
