Answer:
The slope of the line is
⇒ B
Step-by-step explanation:
Let us revise the rule of the slope
The rule of the slope of the line is m =
, where
- (x1, y1) and (x2, y2) are two points lie on the line
∵ The line passes through the point (-3, 1) and point (4, -2)
→ That means one of them is (x1, y1) and the other is (x2, y2)
∴ x1 = -3 and y1 = 1
∴ x2 = 4 and y2 = -2
→ Substitute them in the rule of the slope above to find it
∵ m =
= 
∴ m = 
∴ The slope of the line is 
Answer:
y = -30
Option A
Step-by-step explanation:
y = -2x - 10
y = -5x + 20
We just need to substitute the values of y.
We have to equate both the equation.
-2x -10 = -5x + 20
-2x + 5x = 20 + 10
3x = 30
x = 10
Plug x as 10 in any one of the equation
Let's take the first equation
y = -2x - 10
y = -2(10) - 10
y = -20 -10
y = -30
(5,5730) (7,6022)
slope = (6022 - 5730) / (7 - 5) = 292/2 = 146
y = mx + b
slope(m) = 146
(5,5730)...x = 5 and y = 5730
sub and find b, the y int
5730 = 146(5) + b
5730 = 730 + b
5730 - 730 = b
5000 = b
so ur equation is : y = 146x + 5000 <==
