Question

Use the given conditions to write an equation for the line in​ point-slope form and​ slope-intercept form.

Slope=−2​,

passing through

Answer 1

Hello, Faith,

The question is missing the point that the line passes through. But we can get almost all the way there with what we do know - the slope.

The standard slope-intercept form of the equation for a straight line is y=mx+b, where m is the slope and b is the y-interecept (the value of y when x=0).

We know m is -2. We can write y = -2x+b.

Now we need to find b. If we have one point on the line, we can find b by putting that point (x,y) into the equation. The point is not provided in your question, but we can use an example. For the example, if we are told the line passes through (1,2), we can now solve for b:

2 = -2*(1)+b

b = 4

The equation y =-2x+4 has a slope of -2 and passes through the point (1,2).

For your problem, use the values for x and y for the point given and find b.

I hope this helps,

Bob
