Sagot :

Answer:

[tex]y=x-2[/tex]

Step-by-step explanation:

Slope-intercept form is [tex]y=mx+b[/tex], so if [tex]m=1[/tex], then we have [tex]y=x+b[/tex] and we'll need to plug in [tex](7,5)[/tex] to get [tex]b[/tex], the y-intercept:

[tex]y=x+b[/tex]

[tex]5=7+b[/tex]

[tex]-2=b[/tex]

Therefore, the final equation in slope-intercept form is [tex]y=x-2[/tex]
