Write an equation in slope-intercept form for the line that has a slope of -4/5 and passes through (0, 7).
1 answer:
Answer:
A. y = x + 7
Step-by-step explanation:
Slope intercept form is y = mx + b where m is the slope and b is the y-intercept
<em>It gives us the slope, so we can plug that in:</em> y = x + b
<em>Next, it gives us a point, so we can plug in the x and y into our equation and solve for b when (x, y)</em>
y = x + b
7 = (0) + b
7 = b
<em>Last, complete our equation:</em>
y = x + b
y = x + 7

Answer:
Step-by-step explanation:
Slope intercept formula is y=mx+b
(m) is slope
(b) is the y intercept
We'll find slope first.
slope formula is
y2 and x2 are the y and x values of the second equation and y1 and x2 are the y and x values of the first equation.
So we just put the given values into our equation.
Simplify
Now we put this into our y=mx+b
y=0/-3x+b
now we need the (b)
to do this we take the values of one of the coordinates (doesn't matter which) and replace the (y) and (x) in our equation with them.
Solve
1=0+b
b=1
Put this in our formula
