20 ! 1. which linear equation has a slope of 3 and a y-intercept of –2? y = 3x + 2 y = 3x – 2 y = –2x + 3 y = –2x – 3 2.adriana writes the equation y = 2x + 4 to represent a line on a graph. henry writes an equation that has a y-intercept that is 1 unit lower on the graph but has the same slope as adriana’s line. which is henry’s equation? y = x + 4 y = 3x + 4 y = 2x + 3 y = 2x + 5

it would open into a square depending on the type of envelope i’m not sure about the second part

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
