it's asking to write an equation in slope-intercept form for the line with slope -4 and y-intercept 7. then graph the line. plea
1 answer:
Answer:
Equation = y = -4x+7
See the graph below
Step-by-step explanation:
The equation of the line in slope intercept form is expressed as;
y = mx+c
Given
slope m = -4
y-intercept c = 7
Substitute
y = -4x + 7
Get the x intercept.
at y = 0
0 = -4x + 7
4x = 7
x = 7/4
x = 1.75
The x coordinate (1.75, 0)
Get the y intercept
at x = 0;
y = -4(0)+7
y = 0+7
y = 7
The y coordinate is (0, 7)

The answer is that c3x was the answer
The answers would be (0,10) , (20,0) , and (100,100)
2*_=16
16/2=8
2*8=16
So.. 9*8=72
Therefore Josie got 72 answers correct
Answer:
equation is y = x+4
Step-by-step explanation:
m = 1
y = mx + b
3 = 1*(-1)+b
3 = -1+b
b = 4
so
again
y = mx+b
y = 1x +4
so y = x+4
Solution
Draw the diagram
So using cosine rule
