Answer:

#y=0.5x+7.5#

Explanation:

#"the equation of a line in "color(blue)"slope-intercept form"# is.

#•color(white)(x)y=mx+b#

#"where m represents the slope and b the y-intercept"#

#"here " m=0.5" and " b=7.5#

#rArry=0.5x+7.5" is the equation of the line"#

Answer:

y = 0.5x + 7.5 or 2y = x + 15

Explanation:

The y intercept form of an equation is

# y = mx + b#

m = slope ( think mountain ski slope)

b = y intercept ( Thing beginning where x is zero)

so

m = 0.5

b = 7.5 so

y = 0.5 x + 7.5 multiplying by 2 removes the decimal fractions. so

2y = x + 15
