Question

Will mark brainliest please help me Explain step by step how to find the equation of a line that goes through the points ( 7, 2 ), and ( 0, 4 ). Essay

Answer 1

formula of a linear equasion:

y=mx+b

m=slope of the formula

to find m:

$\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

plug in: $\frac{4-2}{0-7} =\frac{2}{-7}$

m= $-\frac{2}{7}$

y=$-\frac{2}{7}$x+b

b is the y intercept

plug in to find b:

$2=7(-\frac{2}{7} )+b\\2=-2+b\\4=b$

∴ $y=-\frac{2}{7} x+4$

Answer 2

Answer:

Step-by-step explanation:

Put the ordered pairs into the slope formula x=y2-y1/x2-x1 then you will get your slope of the line. once you have your slope pick an ordered pair and put it in point slope y-y1=m(x-x1) distribute and you will get your answer.
