Answer:

Step-by-step explanation:

x2−7x+10=0

Step 1: Factor left side of equation.

(x−2)(x−5)=0

Step 2: Set factors equal to 0.

x−2=0 or x−5=0

x=2 or x=5

(You can confirm this by plugging in the numbers yourself)

How to solve and figure it out
Vilka [71]
So your equation is currently in point-slope form; however, to figure out the slope and y-intercept, you'd be better off in slope-intercept form: y = mx + b

while in point-slope form, y - y1 = m(x - x1), you can definitely see the slope as -5, you can't see the y-intercept as easily. x-intercepts are actually the solutions/zeros of a function, and it was included in the answer choices to confuse you.

you're correct about -5 being a decreasing slope. but to figure out the y-intercept, you need to convert to slope-intercept form.

y - 4 = -5(x + 1)  ... distribute the -5
y - 4 = -5x - 5  ... add 4
y = -5x - 1

and in the form of y = mx + b, where m is the slope and b is the y-intercept, you can see that you have a decreasing slope of -5 and a y-intercept of -1. your correct answer is A. choices C and D were thrown in to distract you and make you think that the -5(x + 1) was somehow related to discovering the x-intercept.

How do I know if the function is a linear function?
Lilit [14]

Answer:

This is not a linear function.

Step-by-step explanation:

It is a quadratic function.  If you were to make a table of the x and y values of the function it would look like this:

x    y

0   -4

1   -1

2    8

Just by looking at these three values, we can see that they do not increase at a consistent rate.  It increases by 3 from 0 to 1, but increase by 9 from 1 to 2.  You can tell if a function is linear by seeing if it increases at a constant rate.  (In this case it does not)
