Slope-intercept form is y=mx+b
m is slope and b is y-intercept.
So, if you have -5x-3y=3
Make it into y=something
So, -3y=3+5x
y= -3/3 + 5/-3 x
y= -1 - 5/3 x
Same as the first one in your pic.
Answer:
x = 2
Step-by-step explanation:
Given
x - 3 = 2 ( add 3 to both sides )
x = 5 ( multiply both sides by 2 to clear the fraction )
5x = 10 ( divide both sides by 5 )
x = 2
Answer:
b = 100°
c = 30°
Step-by-step explanation:
b = 100° bc the two angles are supplementary, that is, together they form a straight angle and add up to 180°.
c = 30°
because a + b + c = 180. There's 180° in a triangle.
