Answer:
Hope this helps!
Step-by-step explanation:
Slope = 5/-2
Slope (m) =
ΔY
ΔX
=
5
-2
= -2.5
θ =
arctan( ΔY ) + 180°
ΔX
= 111.80140948635°
ΔX = -1 – 3 = -4
ΔY = 5 – -5 = 10
Distance (d) = √ΔX2 + ΔY2 = √116 = 10.770329614269
Equation of the line:
y = -2.5x + 2.5
or
y =
- 5 x
2
+ 5
2
When x=0, y = 2.5
When y=0, x = 1
(0,3)(1,-2)
slope = (-2-3) / (1 - 0) = -5
y int is (0,3)
line is dashed, means no equal sign....shading above the line, means greater then
ur inequality is : y > -5x + 3
Answer (<u>assuming it can be in slope-intercept form)</u>:
y = -x - 1
Step-by-step explanation:
When knowing the slope of a line and its y-intercept, you can write an equation to represent it in slope-intercept form, or y = mx + b format. Substitute the m and b for real values.
1) First, find the slope of the equation, or m. Pick any two points from the line and substitute their x and y values into the slope formula,
. I chose the points (0, -1) and (-1, 0):

Thus, the slope is -1.
2) Now, find the y-intercept, or b. The y-intercept of a line is the point at which the line crosses the y-axis. By reading the graph, we can see that the line intersects the y-axis at the point (0,-1), therefore that must be the y-intercept.
3) Now, substitute the found values into the y = mx + b formula. Substitute -1 for m and -1 for b:

Answer:
75.2
