What are the slope and y-intercept of the linear function graphed to the left? slope: –2; y-intercept: 2 slope: ; y-intercept: 1
Anon25 [30]

Let

A(0,1)\\  B(2,0)

we know that

The y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point A is the y-intercept

y=1

<u>The answer part a) is</u>

The value of y-intercept is 1

<u>Part b)</u> Find the slope m

we know that

the value of the slope is equal to

m =\frac{(y2-y1)}{(x2-x1)}

Substitute the values

m =\frac{(0-1)}{(2-0)}

m =-\frac{1}{2}

therefore

<u>the answer Part b) is</u>

The value of the slope is equal to -\frac{1}{2}

<u>The general answer is</u>

The slope is -\frac{1}{2}

The value of y-intercept is 1
