Answer:
y=55
Step-by-step explanation:
First take note a triangle is always equal to a total of 180 degrees
now setup the equation.
y+40+y+30=180
rid of alike terms
70+2y=180
Now subtract 70 from both sides
2y=110
Now divide both sides by 2
y=55
When you have a linear equation of the form y = mx, such as this one, you know immediately that the line passes thru the origin (0,0). Were the form y = mx + b, then the y-intercept would be (0,b) and the x-intercept ( [-b/m, 0).
Answer:
Plug the x-values into the equation to get the y values. This will give you coordinates that you can graph a line with.
Step-by-step explanation:
For x = -5: y = -3 - 2 * (-5) = 7, so the coordinates are (-5, 7)
For x = -2: y = -3 - 2 * (-2) = 1, so the coordinates are (-2, 1)
(Etc.)
Then, plot these coordinates and draw a line through them to complete the graph.
