Answer:
Step-by-step explanation:
The equation to find the slope given 2 points is (y2-y1)/(x2-x1). Lets say that (-5,-2) is x1 and y1 respectively, and (-3,-6) is x2 and y2 respectively. Now, you'd substitute these values into the equation to get [(-6)-(-2)]/[(-3)-(-5)]. When you simplify this, you get (-4/2). When you simplify this further, you get -2. Your slope is -2.

C.
Step-by-step explanation:
Answer:
38°
Step-by-step explanation:
2y+2=3y-16
18=y
3(18)-16= 54-16=38
251 rounded to the nearest hundred is 300
9the equation of a line in ' slope- intercept form ' is
y = mx + c ( m is the slope and c the y-intercept )
y = 3x + 1 is in this form
with slope = 3 and y-intercept = 1
the graph crosses the y- axis at ( 0, 1 )
from this point moving 3 units vertically up and 1 unit horizontally right gives the point (1, 4 ) . Repeating this gives the point (2, 7 )
Plot the points (0, 1 ), (1, 4 ) and (2, 7 )
Draw a straight line through them for graph of y = 3x + 1
