Linear equation is equation in which each term has at max one degree. The function that can represent the given graph is y=2.0769x + 1.5.

<h3>What is linear equation?</h3>

Linear equation is equation in which each term has at max one degree. Linear equation in variable x and y can be written in the form y = mx + c

Linear equation with two variables, when graphed on Cartesian plane with axes of those variables, give a straight line.

For the given graph the equation can be written as, y = mx+c, this is because the graph is a line which means the relationship is linear. Therefore, the equation can be written as,

y = mx + c

Now, there are two points that are on the line and the coordinates of this points are,

A = (4, 9.5)

B = (7.25, 16)

Further the slope of the equation is,

m = (16-9.5) / (7.25 - 4) = 2.0769

Since c is the y-intercept of the graph, therefore, the value of c is 1.5.

Thus, the function that can represent the given graph is y=2.0769x + 1.5.

Consider the proof. Given: In △ABC, BD ⊥ AC Prove: the formula for the law of cosines, a2 = b2 + c2 – 2bccos(A) Statement Reason
loris [4]

Solution: The missing reason in Step 8 is substitution of x=c\cos (A).

Explanation:

The given steps are used to prove the formula for law of cosines.

From step 5 it is noticed that our equation is

a^2=b^2-2bx+c^2      ..... (1)

From step 7 it is noticed that the value of x is c\cos (A).

So by substituting c\cos (A) for x in equation (1) we get the equation of step 8, i.e.,

a^2=b^2-2bc\cos (A)+c^2

Hence, the missing reason in Step 8 is substitution of x=c\cos (A).
