Answer:
the slope of the line in the graph is: 3
the y-intercept is: -4
the equation of the line is: y=3x-4
Step-by-step explanation:
If we find a point on the graph and count it until it reaches other solid point we get that you have to go up three and to the right by one. This solid point I looked at was (0,-4) and counted up to (-1,1). To find the slope, we have to simply count and use "rise over run". The rise is 3 for every 1 we run, making the slope 3/1 which is 3.
the y-intercept is the point on the graph that touches the y-axis on the graph. The only point on the graph that touches the y-axis is -4, making the y-intercept -4.
The equation for a graph is y=mx+b. m would be the slope and b would be the y-intercept. We know that the slope is 3 (m) and that the y-intercept is -4 (b). Putting them together, we get that the equation of the graph is y=3x-4.
Answer:
Graph A
Step-by-step explanation:
≤ (less than or equal to) or ≥ (greater than or equal to) have solid lines because it can be equal to.
< (less than) or > (greater than) have dashed lines because it cannot be equal to.
Less than ( < or ≤ ) = shade under.
Greater than ( > or ≥ ) = shade over.
Answer:
BD = 3.75 units
Step-by-step explanation:
Given AD is an angle bisector then it divides the opposite side into segments tat are proportional to the other 2 sides, that is
= 
, substitute values
= 
( cross- multiply )
8 BD = 30 ( divide both sides by 8 )
BD = 3.75 units
and 
into
