Answer 5

Given: slope = -4 and y-axis intercept is (0, 3).
.
Problem: Write the equation.
.
The form you are looking for is called the slope-intercept form of an equation. It is written as:
.
y+=+mx+%2B+b
.
and in this equation "m" [which is the multiplier of "x"] is the slope and "b", a constant,
is the value of y when x is zero. It is called the y-intercept because it is the value of y
where the graph of the equation crosses the y-axis.
.
Start with the slope intercept form:
.
y+=+mx+%2B+b
.
Since m is the slope and the problem tells you that the slope is -4, you can just substitute
-4 for m and the equation becomes:
.
y+=+-4x+%2B+b
.
The problem also tells you that b, the value of y when x = 0, is +3. Substitute this into the
equation and you get:
.
y+=+-4x+%2B+3
.
That's the equation you were asked to find. Hope this explanation helps you to understand
the slope-intercept form of the equation of a straight line and what the numbers in that
form refer to.

Answer 6

y+-4x+3

Answer 7

or 1.- Write the equation of the line with a slope of -5 and a y-intercept of (0,3)

it means m = -5 and b = 3
if you're looking for y = mx + b you get
y = -5x + 3

- - -

3.- Write the equation of the line passing through the points (0, -4) and (-2, 2).


Point 1 = ( 0, -4 )
Point 2 = ( -2, 2 )

y = mx + b
m = (y2 - y1) / (x2 - x1)

In your case y2 = 2 , y1 = -4 , x2 = -2 , x1 = 0
m = -3
b = -4

it means y = -3x - 4

Answer 8

\[y=-4x+3\]

Answer 9

sorry yall my internet is lagging bad they all just came thru

Answer 10

so my equation is y=-3x-4

Answer 11

@bohotness

Answer 12

\[y+mx+b\]and in this equation "m" [which is the multiplier of "x"] is the slope and "b", a constant,
is the value of y when x is zero. It is called the y-intercept because it is the value of y
where the graph of the equation crosses the y-axis.
