PLEASE HELP!! The slope of the line below is 2.5. Write the equation of the line in point-slope
Kisachek [45]

Answer:

y = 2.5x

Step-by-step explanation:

y = mx + b

m=2.5 (slope) -->  y=2.5x+b

coordinate : (2,5) 2 is the x coordinate, 5 is the y coordinate

to Find b, input the coordinate --> 5 = 2.5(2) + b

                                                        5 = 5 + b

                                                        0=b

y= 2.5x

This is only since it asked to solve using the point. If you look at the graph, the line intercepts the y-axis at (0,0) so b=0.

hope this helps

dangina [55]

Answer:

Angles 7, 2, and 6

Step-by-step explanation:

       Angle 7 is congruent by corresponding angles to angle 3.

       Angle 2 is congruent by vertical angles to angle 3.

       Angle 6 is congruent by vertical angles to angle 7, which is congruent to angle 3, so angle 3 and angle 6 must also be congruent.
