Answer:
y = 2/5x + 5
Step-by-step explanation:
I assume you want the equation in point slope form? So assuming that, (0, 5) is the y intercept which is b in the equation y=mx+b (b=5). Now you have to find the slope, paper is really handy (I like drawing a graph out to help me sometimes but an easy way to do it is another equation like this...
y2-y1/x2-x1=
7-5/-5-0=
2/5 --> So 2/5 is the slope, and that finishes the equation
Final equation in point slope form: y=2/5x+5
HOPE YOU UNDERSTAND NOW!!!! :)
Answer:
27.5
Step-by-step explanation:
70(0.80)^10 + 20 = 27.51619276 which s about 27.5
Answer:
Slope=4 y-intercept=(0,-21) or -21
Step-by-step explanation:
To find<u> slope</u>
m=-13-(-17)/2-1
m=4/1
m=4
To find <u>y-intercept</u>
y-(-17)=4(x-1)
y+17=4(x-1)
y+17=4x-4
Subtract both sides by 17
y=4x-21
y-intercept=-21
