-9 -4x = 7
add 9 to both sides in order to isolate the x
-4x = 16
divide by -4
x = -4
Standard form : -5a+75
leading co is: -5

Answer:
a. m = 2; y intercept = (0, 4); y = 2 x + 4
Step-by-step explanation:
The slope can be found using the formula ...
m = (y2 -y1)/(x2 -x1)
m = (18 -4)/(7 -0) = 14/7
m = 2
The y-intercept is the first given point: (0, 4).
The equation for the line in slope-intercept form is
y = mx + b
Here, we have m=2 and b=4, so the equation is ...
y = 2x +4
Answer: c and e
explanation: put the equation in the graphing calculator and look at the graph and table the answer will show
