Answer:
y= -2/5 x -4
Step-by-step explanation:
So the equation is y=mx+b. Where m=slope and b=y-intercept. To find b, you would see at what point does the line cross the y axis. That would be at -4 so, -4 would be the b or y-intercept. To find m, you would take two points on the line and use this equation:
m=(y2 - y1 )/(x2 - x1)
If you were using the points, (-10,0) and (0, -4) the equation would be:
m=(-4-0) / (0+10)
So, m= -2/5
The equation of the line would end up being:
y= -2/5 x -4
Answer:
4(x-2)(x+1)=0
Step-by-step explanation:
The point-slope equation of the line is 
Step-by-step explanation:
The form of the point-slope equation is 
, where
- m is the lope of the line
is a point lies on the line
The slope of a line 
, where
and 
are two points on the line
∵ The line through (2 , 3) and (7 , 4)
∴ 
= 2 and 
= 7
∴ 
= 3 and 
= 4
- Substitute these value in the rule of the slope
∵ 
∴ the slope of the line is 
Let us substitute the value of the slope and the coordinates of point in the form of the equation
∵
∵ = 2 and = 3
∵
∴
The point-slope equation of the line is

Answer:
-22
Step-by-step explanation:
-18 - 4 =
We are subtracting both number so add them and then give them a negative sign
-( 18+4)
-22
