Question

I need help urgenty 50 % of grade

Answer 1

☑ y-intercept

Explanation:

» Considering the general linear equation:

`\hookrightarrow \: { \tt{y = mx + c}}`

• m is the slope
• c is the y-intercept
• x and y are coordinates of any point plotted on a line.

» Then back to our question, compare the both equations;

`{ \tt{y ={ \green{ m}}x + { \green{c}} }}\\ \downarrow \\ { \tt{y = { \green{0.23}}x + { \green{225}}}}`

• 0.23 is the slope
• 225 is y-intercept.

[ In some proportional equations, 225 can be an additional constant ]

Answer 2

Option A and B

Explanation:

change in pounds lifted per day?

• If every day the weight got increased by 225 then it's applicable

Initial amount of pounds weighted on day 0

• First day he started with 225 and every day it's got increased by 0.23
