What is the equation of the line that passes through
(-2, 4) and (2, 7)?

Step-by-step explanation:

Hi there!

We want to find the equation of the line that passes through (-2, 4) and (2, 7).

The most common way to write the equation of the line is in slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept.

First, let's find the slope of the line.

The slope, calculated from two points is given as the formula , where and are points.

We have two points, which is needed to find the slope, but let's label their values to avoid confusion.

Now substitute those values into the formula.

m=

m=

Simplify

m=

m=

So the slope of the line is .

Substitute that value as m in y=mx+b

y=

Now we need to find b

As the equation passes through both (-2, 4) and (2, 7), we can substitute the values of either one of them in the equation to solve for b

Taking (-2, 4) for example,

Substitute -2 as x and 4 as y:

4=

Multiply

4=+b

Add -3/2 to both sides

Substitute that value into the equation

y=

Hope this helps!

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.
