Answer:

#16 has the greatest y - intercept,

Step-by-step explanation:

the y - intercept is the number that comes after x in y = ?x + ?

The equation is y = mx + b, where m is the slope and b is the y - intercept.

#13 has a y - intercept of 5, #14 has 0, #15 is 2, and #16 is 6

The y - intercept is the value of y when x is 0, or where the line is on the y -axis

Write an equation of the lines passes through (4,1) and is parallel to y= -2x+7
Nastasia [14]

Answer:

y = -2x + 9

Step-by-step explanation:

The parallel line has an equation of y = -2x + 7;

And its slope is -2.

The slope of the line that passes through (4,1) is also -2 since parallel lines have the same slope.

Taking another point (x,y) on the line that passes through (4,1):

slope(m) = change in y ÷ change in x

-2 = \frac{y - 1}{x - 4}

Cross multiplying gives;

y - 1 = -2x + 8

y = -2x + 9

Write the equation of the line that passes through the points (6,2) (4,1)
Alisiya [41]

Answer: y=1/2x-1

Step-by-step explanation:

To find the equation of the line that passes through the points, we need to find out slope, m.

m=\frac{y_{2} -y_{1} }{x_{2}-x_{1}  }

We plug our points into this formula to find slope.

m=\frac{1-2}{4-6} =\frac{-1}{-2} =\frac{1}{2}

Our slope is 1/2. To find our y-intercept, b, we would plug any point into the equation for slope-intercept form.

y=mx+b

y=1/2x+b

1=1/2(4)+b

1=2+b

b=-1

Now that we know b, our equation is y=1/2x-1.
