Answer:
a. y = -5x + 4
Step-by-step explanation:
Given the following data;
Slope, m = -5
Intercept, c = 4
Mathematically, the equation of line is given by the formula; y = mx + c
Where;
m is the slope.
x and y are the points
c is the intercept.
Substituting the given parameters, we have;
y = -5x + 4
Answer:

Step-by-step explanation:
a^2+b^2=c^2
5^2+b^2=16^2
25+b^2=256
b^2=231
b=
Answer:
Graph C
Step-by-step explanation:
Graph C shows a linear relationship
Answer:
x^2 + 1.1x + 0.28
Step-by-step explanation:
4x+8y=40
0.8*8=6.4
4x+6.4=40
40-6.4=33.6
4x=33.6
33.6\4=8.4
X=8.4
