Answer:
y=2x-58
Explanation:
In order to write our point-slope formula (y=mx+C format), we first need to figure out the slope (m). To figure out the slope, we divide the change in y by the change in x between the two points (rise/run). The rise is 30 (2-(-28)) and the run is 15 (30-15). Therefore the slope is 2 (30/15)
This gives us:
y=2x + c
Now to figure out C (which will be the y-intercept of the graph) we substitute in the values from one of the points. So our x=30 and our y=2:
2=2(30) + c
2=60+c
2-60=c
-58=c
So now we know that our C (constant) is - 58.
Hence our point-slope formula is:
y=2x-58
Which you can test with the other point:
-28=2(15) - 58
Hope this helped!
B. 10+3x=5
3x=-5 (subtract 5 both sides)
X=. -5/3 (divide both sides by 3)
C. A+x = b
X = b-a (just get x alone)
D. Cx = d
X = d/c
Answer: a=-5
Step-by-step explanation:
2(a + 3) = −4
2a+6=-4
2a=-10
a=-5
