How do you write an equation of a line given 2 points?

write the equation for the line containing points (3,8) and (9,2).

convert the equation to slope intercept form.

x+y=11

y=-x+11

Step-by-step explanation:

In order to solve this we first have to find the slope of the function, remember the formula of the slope:

The slope is -1, based on this we can calculate the formula for the equation with the general function:

y-y1= M(x-x1)

y-8=-1(x-3=

y-8=-x+3

y+x-11=0

Now in the slope form you just clear y from the equation:

y=-2-x+11

So that is the answer to the question.

the fist one is not equalvalent but i think th second one isand the third isnt definetly or the last one is i think. hope this !

step-by-step explanation:

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
