y=mx+b is the equation of a line;
m=slope , b= y-intercept
You can find the slope with this following equation: (y(2)-y(1))/(x(2)-x(1))
In this case the points are (0,4) and (-2,-3). The first set being (0,4) and the second (-2,-3). This means (0,4) can be expressed as (x(1),y(1)) and (-2,-3) expressed as (x(2),y(2)). Plugging these numbers into the slope equation gives us: (-3-4)/(-2-0) = -7/-2 = 7/2.
m= 7/2 ; so we have : y= (7/2)x+b
We are give a set of points which it passes through, we can simply plug them in:
4 = (7/2)(0)+b (0 is the x and 4 is the y)
We get 4 = 0 +b .... 4=b
our final equation is : y=(7/2)x+4
Answer:
1
Because 9/3= 3
And 3-2=1
Hence the answer is 1
Step-by-step explanation:
-7 - 7( 8x - 7 ) = -19 + 5x
⇔ -56x + 49 = -12 + 5x
⇔ -61x = -61
⇔ x = 1
Answer:
D
Step-by-step explanation:
if each dot is one person then there are only 2 people that are 12 and that are more than 60in tall
Answer:
y = 4/7x - 4
Step-by-step explanation:
You first have to put it in y = mx + b form
So, we first subtract 4x from both sides: -7y = -4x + 28
Divide both sides by -7
y = 4/7x - 4
Now to graph you have to start at the starting point which is -4
So we start with our point on -4 then move up 4 times and 7 times to the left. Mark the points then draw your line!
