Answer:
Sum of two consecutive angle is always 180°
Step-by-step explanation:
In a parallelogram what we can you say about the consecutive angle is that they are supplementary to each other. By supplementary we mean that the sum of the two angles is always 180°
Answer:

Step-by-step explanation:
The slope of a graph is also known as its gradient, which is the steepness of the graph.
If we are given two points on the line, we can find the slope by taking rise/ run, which is the ratio of the change in y-coordinate against the change in the x-coordinate. This can also be written as a formula:

☆ (x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate
In this question, we are given the equation of the line. This equation is already in the slope-intercept form (y= mx +c) since the coefficient of y is 1 and all the other terms are on the other side of the equal sign. In the slope-intercept form, m is the slope while c is the y-intercept.
m= ⅘ since the coefficient of x is ⅘ in the given equation (when the equation is in the slope-intercept form).
5(2x-3)-(x+8)=13
10x-15-x-8=13
9x-23=13
9x=36
x=4
Answer:
-1
Step-by-step explanation:
The formula to find the slope of a line is:

where (x1, y1) and (x2, y2) are points on the line. We can substitute the points (-10, 0) and (-13, 3) into the formula and simplify:

This means the slope of the line is -1.
