Graph: y= -1/2x List two points on your line?

Question

I need someone to check my answer of

Point 1: (0, -1)
Point 2: (0,-1)

If this is incorrect, please explain with detail how to solve for this. Thank you.

Answer 1

y = - 1/2x

x = 0

y = - 1/2(0)

y = 0/2

y = 0

When x is 0 y is 0
- - - - - - - -

x = 1

y = - 1/2(1)

y = - 1/2

y = - 0.5

When x is 1 y is - 0.5
- - - - - - - -

x = 2

y = - 1/2(2)

y = - 2/2

y = - 1

When x is 2 y is - 1

- - - - - - - - - -

x = 3

y = - 1/2(3)

y = - 3/2

y = - 1 1/2

y = - 1.5

When x is 3 y is - 1.5

- - - - - - -s-

Answer 2

Well first off you listed the same point twice which probably doesn't count for your assignment. Also the point (0,-1) is not on the line.

To find any point on a line pick a number for x

Then Plug that number into the equation in place of x

Then solve for y


For example: If I let x equal 4

than I replace x with 4 giving y=-1/2(4)

So in order to solve for y you just multiply -1/2 times 4 and you get -2. So one point on the line would be (4,-2)

It doesn't matter what number you pick for x as long as you do the math right.

I hope this helps


Note: You could also start by choosing a number for y and solving for x.

Answer 3

point1 is the same with point 2 and it is not on graph

if x = 0 then y = -1/2*0 = 0
Point 1:(0,0)

if x= 2 then y = -1/2*2 =-1

Point 2:(2,-1)

Answer 4

ok, firstly The equation y =mx+b is in basic terms a formula to help plot a line on a graph the place you be attentive to the two the slope and y-intercept, the slope and another element( y-y1)=m(x-x1) the place the element (x1,y1) isn't the y-int., or you in basic terms be attentive to 2 factors on the line (x1,y1),(x2,y2). one million. y=mx+b y=3x+5 look commonplace? what's m interior the 2nd equation? what's b? 2. comparable as #one million in basic terms you're given m and b 3. a touch trickier, yet no longer too undesirable. you're easily given b interior the situation (0,one million) remember b = y-intercept or element the place line crosses y-axis. What you may desire to discover is the slope of the line. The slope is the exchange in y divided with the aid of exchange in x or, upward thrust over run. The formula is (y2-y1)/(x2-x1). subsequently, (2-one million)/(0-one million), which provides a slope of one million/2. So, m= one million/2 and b = what? (remember, the y-intercept is (0,one million) meaning that b = one million. 4. persist with the comparable steps above to discover the slope after which use the formula (y-y1) = m(x-x1) As a conventional rule, I constantly assign (x1,y1) as a results of fact the 1st element given in a situation, which subsequently is (-one million,3). wish this enables!
