Answer:
c=7
Step-by-step explanation:
−5c+5=4c−58
Subtract 4c from both sides.
−5c+5−4c=4c−58−4c
−9c+5=−58
Subtract 5 from both sides.
−9c+5−5=−58−5
−9c=−63
Divide both sides by -9.
-9c/-9= -63/-9
c=7
Answer:
y = 7x - 2
Step-by-step explanation:
first we need the slope of the line.
the slope is expressed a the ratio (y coordinate change / x coordinate change) when we go from one point on the line to another.
so, let's say we go from (0, -2) to (1, 5), we see
x changes by +1 (from 0 to 1).
y changes by +7 (from -2 to 5)
so the slope is +7/+1 = 7
the slope-intercept form is in general
y = ax + b
a being the slope, b being the y-intercept (the y-value for x = 0).
the point (0, -2) gives us therefore the y-intercept directly : -2.
by using the already established slope and the point (0, -2) for the y-intercept the equation of our line is
y = 7x - 2
2 - 0.002= 1.998
hope this helps
