How do you write the equation of a line with slope 0.5 and y-intercept 7.5?
#"the equation of a line in "color(blue)"slope-intercept form"#is.
#"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"#
y = 0.5x + 7.5 or 2y = x + 15
The y intercept form of an equation is
m = slope ( think mountain ski slope)
b = y intercept ( Thing beginning where x is zero)
m = 0.5
b = 7.5 so
y = 0.5 x + 7.5 multiplying by 2 removes the decimal fractions. so
2y = x + 15
