Answer:
Whats the question ;-;
Step-by-step explanation:
Slope of the line =
.
y-intercept of the line = -7.
Solution:
General form of equation of a line:
y = mx + c
where m is the slope and c is the y-intercept of the line.
Equation of a line:

To compare this with general equation.


Slope of the line =
.
y-intercept of the line = -7.
Divide I from both sides then subtract r from both sides, too so in the end:
R= (E-r)/I
